The EBC Trek with Island Peak Climbing combines two objectives that most trekkers treat as separate expeditions. In 19 days we walk the full Everest Base Camp route to 5,364 m, summit Kala Patthar at 5,545 m, and then continue into the upper Imja Valley to climb Island Peak (Imja Tse) at 6,187 m. The summit of Island Peak delivers a 360-degree panorama of Ama Dablam (6,812 m), Lhotse (8,516 m), Makalu (8,485 m), and Baruntse (7,129 m) that no lower viewpoint in the Khumbu can match.
Island Peak was named by Eric Shipton during the 1952 British reconnaissance expedition. Looking up from the Imja Valley, the mountain appeared to float like an island above a sea of ice, a description that has held for 70 years. The Sherpa name, Imja Tse, comes from the Imja Glacier it overlooks. At 6,187 m it sits just below Nepal Mountaineering Association’s Category A peak threshold, which means no expedition permit is required, only a trekking peak permit, which we handle for you. It is the most frequently climbed peak above 6,000 m in Nepal and the standard entry route for anyone moving toward larger Himalayan objectives.
Why This Combination Works
The EBC route and Island Peak share the same approach corridor from Lukla to Namche Bazaar and Tengboche. The routes diverge at Dingboche, where EBC trekkers continue toward Lobuche and Gorak Shep while Island Peak climbers branch east through Chhukung. By completing EBC and Kala Patthar first, you arrive at Island Peak Base Camp with 17 days of high-altitude acclimatization already in your legs, the best possible preparation for a 6,000 m summit attempt.
We include two acclimatization stops: Namche Bazaar at 3,440 m (Day 4) with a hike to the Everest View Hotel at 3,880 m, and Dingboche at 4,410 m (Day 7) with a hike to Nangkartshang Peak at 5,083 m. By the time you stand at Island Peak Base Camp at 5,240 m on Day 12, your body has already been above 5,000 m twice.
Our certified high-altitude climbing Sherpa leads the Island Peak summit attempt. He provides a climbing skills briefing at base camp covering crampon technique, rope management, ascender use, and headwall protocols. Fixed ropes are placed on the summit headwall, the steepest section of the climb, for safety on both ascent and descent.
Island Peak, Technical Details
Island Peak has three distinct sections. The approach from base camp to high camp crosses glacier moraines and a lower snowfield. The middle section is a moderate-angle snowfield at around 25 to 30 degrees where crampons and trekking poles are the primary tools. The summit headwall is the technical crux: a 50 to 60-degree ice wall approximately 150 metres high where fixed ropes and an ascender are required. Most fit, prepared climbers without prior technical experience complete this section in two to three hours.
The summit itself is a narrow snow ridge at 6,187 m. In clear conditions you see the full Khumbu range from a perspective that is higher than Kala Patthar and deeper in the mountains. Lhotse’s south face fills the horizon to the north. Ama Dablam rises like a cathedral above the Imja Valley behind you. Makalu and Baruntse close out the eastern panorama.
We leave base camp between midnight and 1:00 a.m. for the summit. The pre-dawn start is calculated to reach the headwall before the sun softens the ice, firm snow gives better crampon purchase and reduces rockfall risk from freeze-thaw loosening.
The Full 19-Day Route
Days 1 and 2 are Kathmandu arrival and preparation. On Day 2 we fly to Lukla (2,860 m) and trek to Phakding (2,652 m). Days 3 to 5 bring us through Namche Bazaar (acclimatization) to Tengboche and Dingboche. Day 7 is the second acclimatization day at Dingboche with the Nangkartshang hike.
Days 8 and 9 follow the classic EBC route via Lobuche to Gorak Shep and then to Everest Base Camp. Day 10 is Kala Patthar before dawn, then a long descent to Dingboche. Day 11 moves to Chhukung (4,730 m), the last settlement before Island Peak Base Camp. Day 12 is the trek to base camp. Day 13 is summit day, nine to ten hours round trip from base camp. Day 14 is a weather spare and recovery day. Days 15 to 18 descend via Chhukung, Tengboche, Namche, and Lukla for the return flight. Day 19 is departure from Kathmandu.
Best Season
We run this expedition in spring (mid-March to late May) and autumn (late September to mid-November). October is the most reliable month: post-monsoon stability, excellent summit visibility, and Island Peak snow in ideal condition. April is the spring peak: slightly warmer temperatures and fewer crevasse hazards on the lower glacier. We do not run the Island Peak climb in monsoon or winter, the headwall becomes dangerously avalanche-prone in both conditions.
Permits
This package requires four permits. The Sagarmatha National Park entry fee is USD 30, the TIMS card is USD 10, and the Khumbu Pasang Lhamu Rural Municipality fee is NPR 2,000. The Island Peak climbing permit from the Nepal Mountaineering Association costs USD 125 per person for the autumn season and USD 70 per person for spring. All four are included in your package price and handled by our Kathmandu office before departure.
Trekking and Climbing with Everest Trekking Company
We have been operating in the Khumbu since 2004 and have led Island Peak summits every season since 2008. Our senior trek leader Susam Suywal has summited Island Peak more than 30 times and treats each departure with the same technical preparation as the first. Every climber on this package is assigned a dedicated certified high-altitude climbing Sherpa in addition to the trekking guide, one-to-one climbing support on the headwall is our standard, not an optional extra.
We carry a full medical kit including a Gamow bag and pulse oximeters on every departure. Island Peak is demanding but it is achievable for any well-prepared trekker who completes the EBC acclimatization properly, we have the track record to show it.
2026 Update: Lukla Flights and Permit Fees
Trekkers joining Everest Trekking Company in spring 2026 (March to May) should note that Lukla flights during the peak spring season often depart from Ramechhap airport rather than Kathmandu’s Tribhuvan International Airport. Ramechhap is approximately 3 hours by road from Kathmandu. We arrange shared jeep transfers for all groups departing from Ramechhap. Autumn departures (September to November) typically fly directly from Kathmandu.
Permit fees for 2026 remain: Sagarmatha National Park entry at NPR 3,000 (approximately USD 22) per person, and the Khumbu Pasang Lhamu Rural Municipality fee at NPR 3,000 (approximately USD 22) per person. Both are included in your Everest Trekking Company package price. A TIMS card (Trekkers Information Management System) is also included at NPR 2,000 (approximately USD 15).

Your Everest Trekking Company representative meets you at Tribhuvan International Airport and transfers you to your hotel in Thamel. In the evening we hold a full pre-expedition briefing covering the 19-day itinerary, Island Peak technical overview, equipment check, and permit paperwork. Bring two passport-size photos and your travel insurance certificate to this meeting. Overnight at a 3-star hotel in Kathmandu.
Early morning departure for the domestic terminal for the 35-minute flight to Lukla’s Tenzing-Hillary Airport. From Lukla we follow the Dudh Koshi river downstream to Phakding, an easy three to four hours on mostly flat trail. Porters are assigned here: one porter per two trekkers for the teahouse section, transitioning to our base camp kitchen crew at Chhukung. Overnight in Phakding.
Five to six hours from Phakding to Namche, entering Sagarmatha National Park at Monjo where rangers check permits. The trail crosses the Hillary Bridge above the Dudh Koshi river before the steep 800-metre ascent to Namche at 3,440 m. First views of Everest above the ridgeline are often visible from the upper trail on arrival. Overnight in Namche.
We leave at 7:00 a.m. for the two-hour hike to the Everest View Hotel at 3,880 m. From the hotel terrace you see Everest (8,849 m), Lhotse (8,516 m), Ama Dablam (6,812 m), and Thamserku (6,618 m) before morning cloud fills the valley. Back in Namche by 10:30 a.m. for the afternoon: visit the Sherpa Culture Museum, check gear at the shops, or rest. This acclimatization stop is the first of two critical altitude-adaptation days before the Island Peak summit. Overnight in Namche.
The trail descends from Namche to the Dudh Koshi at Phunki Tenga before climbing 600 metres through rhododendron and juniper forest to Tengboche ridge. Tengboche Monastery (founded 1916) sits on the ridge with Ama Dablam rising directly behind it and Everest visible above the Nuptse Ridge. If timing aligns with monastery prayer hours, the puja ceremony adds a distinctive cultural dimension to the trek. Four to five hours walking. Overnight in Tengboche.
We cross the Imja Khola and enter the Imja Valley, diverging from the main Lobuche trail at Pangboche. The upper Imja Valley opens into wide stone-walled yak pastures and Ama Dablam grows closer with each hour of walking. Dingboche at 4,410 m is a picturesque settlement surrounded by dramatic peaks and serves as the base for our second acclimatization day. Five to six hours walking. Overnight in Dingboche.
The second and higher acclimatization day. We climb to Nangkartshang Peak at 5,083 m, roughly 670 metres above Dingboche, on a four to five hour round hike. The view of Ama Dablam from Nangkartshang is one of the finest close-up mountain perspectives in the Khumbu. More importantly, this is your first time above 5,000 m, a physiological benchmark that matters for Island Peak acclimatization. Pulse oximeter readings are taken at the summit. Overnight in Dingboche.
We rejoin the main EBC trail above Thukla, passing the stone memorial chortens built in honour of climbers who died on Everest, a moving and sobering stretch of trail. The route runs along the Khumbu Glacier lateral moraine to Lobuche at 4,940 m. Pumori (7,161 m), Nuptse, and Lobuche Peak dominate the skyline. Five to six hours walking. Overnight in Lobuche.
Along the Khumbu Glacier moraine to Gorak Shep in two to three hours. We drop bags and continue to Everest Base Camp (5,364 m), a two-hour return walk across the rocky ice of the lower Khumbu Glacier. Base Camp sits at the confluence of the glacier and the Khumbu Icefall, in expedition season you see tents, fixed ropes trailing up the icefall, and the entire machinery of an Everest attempt. We return to Gorak Shep for dinner and overnight. Six to seven hours total. Overnight in Gorak Shep.
Up at 4:00 a.m. for the Kala Patthar summit (5,545 m) at dawn. The 400-metre climb from Gorak Shep takes one to one-and-a-half hours; from the top you see Everest’s south face at a distance and angle unmatched by any other trail viewpoint in the Khumbu. After breakfast at Gorak Shep, we descend the full way to Dingboche, a long, tiring, but predominantly downhill day. Seven to eight hours total. Overnight in Dingboche.
A short three to four hour walk through alpine meadows and yak pastures in the Imja Valley to Chhukung at 4,730 m. Chhukung is the last permanent settlement before Island Peak Base Camp and the final point to check gear, rest legs, and eat well before the mountain section begins. Ama Dablam fills the southern skyline. Your climbing Sherpa conducts a gear check here for all technical equipment. Overnight in Chhukung.
We leave the teahouse trail and move onto the Island Peak moraine, following the Imja Glacier to Base Camp at 5,240 m. The four to five hour walk gains around 500 metres of elevation on rocky terrain. Base Camp is a flat area on the glacier edge sheltered by a rock wall. We sleep in tented camp here, our kitchen crew has meals prepared. Your climbing Sherpa briefs the group on tomorrow’s route, reviewing the three sections: lower glacier, snowfield, and headwall. An early night is essential. Overnight in tented camp at Island Peak Base Camp.
We leave camp between midnight and 1:00 a.m. by headlamp. The first hour crosses the lower glacier on crampons. The next two hours climb the main snowfield at roughly 25 to 30 degrees, sustained but not technical. At the base of the headwall we rope up. The headwall is a 50 to 60-degree ice wall approximately 150 metres high; our climbing Sherpa has installed fixed ropes and leads each climber up in turn with the ascender clipped to the line. Most climbers take two to three hours on the headwall. The summit ridge at 6,187 m is narrow, we take the view, photographs, and descend. The panorama includes Ama Dablam, Lhotse, Makalu, Baruntse, and the full spread of the upper Khumbu. We descend to Chhukung by mid-afternoon. Nine to ten hours total. Overnight in Chhukung.
This day is held in reserve for bad weather on summit day. If conditions on Day 13 forced a delay, storm, high wind, or poor visibility on the headwall, we make the summit attempt today instead. If the summit was reached on Day 13, this day becomes a full rest and recovery day at Chhukung. Even if the legs feel good, rest here is valuable before three consecutive descent days. Overnight in Chhukung.
A long descent day: six to seven hours from Chhukung at 4,730 m back down through Dingboche, Pangboche, and across the Imja Khola to Tengboche at 3,860 m. Each 500 metres of elevation loss at this stage of the trip produces a noticeable improvement in energy, appetite, and breathing. The valley views on the descent are expansive and light at this altitude is softer than at base camp. Overnight in Tengboche.
From Tengboche we descend steeply through juniper and rhododendron forest to Phunki Tenga, cross the Dudh Koshi, and climb the opposite valley wall via Khumjung (3,780 m), a traditional Sherpa village with a famous yeti scalp displayed at the local monastery. Namche Bazaar is reached in the early afternoon. Hot showers, bakeries, and phone signal feel like significant luxuries at this point. Five to six hours walking. Overnight in Namche.
The final day on the trail. Six to seven hours from Namche, reversing the first days of the trek back down the Dudh Koshi valley. We arrive in Lukla by mid-afternoon. This is the time to settle final tips with your guide and climbing Sherpa and to celebrate what you have done over the past 17 days on the trail. Overnight in Lukla.
Morning flight from Lukla to Kathmandu (35 minutes). We transfer to the hotel and have the day free in Kathmandu. Farewell dinner in the evening with your guide and climbing Sherpa. Overnight at a 3-star hotel in Kathmandu.

Island Peak (Imja Tse) is a 6,187 m peak in the Khumbu region of Nepal. It was named by Eric Shipton during the 1952 British reconnaissance expedition because, seen from the Imja Valley, it appeared to rise like an island above a sea of glacier ice. At 6,187 m it is Nepal’s most frequently climbed peak above 6,000 m and is widely considered the best introduction to Himalayan mountaineering, technical enough to require ropes and crampons but achievable by fit, prepared trekkers without prior mountaineering experience. The summit gives a 360-degree panorama of Ama Dablam, Lhotse, Makalu, and Baruntse.
No prior technical climbing experience is required, but you need to be physically strong and mentally comfortable with exposure. Island Peak has one genuinely technical section: the summit headwall, a 50 to 60-degree ice wall approximately 150 metres high. Our certified climbing Sherpa fixes ropes on this section and leads each climber with an ascender clipped to the fixed line. The technique is straightforward but the angle is steep. At base camp your climbing Sherpa conducts a full skills briefing covering crampon technique, harness fitting, ascender use, and headwall safety. Climbers who complete the EBC acclimatization properly and arrive at base camp with reasonable upper-body strength consistently succeed on this route.
All technical climbing gear is included in your package price: crampons, climbing harness, ascender, belay device, locking and non-locking carabiners, and climbing helmet. Fixed rope installation on the summit headwall is also included. You need to bring or rent mountaineering boots, plastic double boots or very stiff-sole trekking boots with steel crampons are required. Soft trail-running shoes or standard trekking boots are not suitable. Mountaineering boots can be rented in Kathmandu’s Thamel district for approximately USD 20 to 30 per day. General climbing items like ice axe and gaiters are also required and can be rented in Kathmandu.
The 19-day itinerary is built around progressive acclimatization for Island Peak. The first stop is Namche Bazaar at 3,440 m (Day 4) with a hike to the Everest View Hotel at 3,880 m. The second is Dingboche at 4,410 m (Day 7) with a hike to Nangkartshang Peak at 5,083 m, your first time above 5,000 m. Days 9 and 10 reach Everest Base Camp at 5,364 m and Kala Patthar at 5,545 m, giving you two days above 5,300 m. By the time you reach Island Peak Base Camp at 5,240 m on Day 12, you have 17 days of cumulative altitude exposure. This is significantly better preparation than a standalone Island Peak trip without EBC acclimatization.
With proper acclimatization and good weather, experienced operators report summit success rates of 75 to 85% for parties that reach Island Peak Base Camp in good condition. The main limiting factors are weather (high wind and new snow on the headwall), individual acclimatization responses, and physical fatigue late in the trip. We include one spare day at base camp specifically to allow a second summit attempt if Day 13 conditions are not safe. We do not push clients up the headwall in unsafe conditions, turning back is part of the plan, not a failure.
The Island Peak climbing permit is issued by the Nepal Mountaineering Association (NMA). The cost is USD 125 per person for the autumn season (September to November) and USD 70 per person for the spring season (March to May). The permit is included in your ETC package price. Our Kathmandu office processes all four permits before departure: Sagarmatha National Park (USD 30), TIMS (USD 10), Khumbu Pasang Lhamu Rural Municipality (NPR 2,000), and the Island Peak climbing permit. You receive all physical permit cards on Day 2 before flying to Lukla.
Island Peak Base Camp at 5,240 m does not have permanent teahouse accommodation. We camp in tented camp with sleeping tents and a mess tent. Our kitchen crew cooks full meals, breakfast, lunch, and dinner, at base camp using equipment carried up from Chhukung. The camp is sheltered on a moraine flat and is well established by spring and autumn season operators. Temperatures at night at 5,240 m drop to minus 10 to minus 15°C in October, so a sleeping bag rated to at least minus 15°C is essential. We supply the tent; you bring your sleeping bag.
We include one spare day at base camp (Day 14). If conditions are poor on summit day (Day 13), high wind, fresh snow, poor headwall visibility, we wait and attempt the summit on Day 14. If conditions remain unsafe through Day 14, we descend without a summit attempt. A failed summit attempt due to weather or conditions beyond our control is not a reason for a refund; it is an inherent part of high-altitude mountaineering. We strongly recommend travel insurance that covers expedition cancellation and non-completion.
This is the most demanding itinerary in our Khumbu portfolio. The ideal participant is an experienced trekker who has ideally been above 4,000 m before, has strong cardiovascular fitness, and is comfortable with the idea of technical terrain at altitude. You do not need prior mountaineering experience. You do need: at minimum 12 weeks of dedicated cardio training before departure (running, hiking, cycling), comfort sleeping in cold conditions, and the mental resilience to perform on a summit day after 12 days on the trail. Trekkers in their 20s to 60s complete Island Peak successfully every season, fitness and preparation matter more than age.
Travel insurance is mandatory for all participants on this trip. The policy must explicitly cover trekking and mountaineering to 6,200 m elevation and include emergency helicopter evacuation. Standard travel insurance policies that exclude mountaineering above 4,000 m or 5,000 m are not sufficient. Bring a printed copy of your insurance certificate with emergency contact number and policy number to the Day 1 briefing, our staff records this for the rescue coordination file. Without valid insurance at the correct altitude, we reserve the right to refuse to take you on the Island Peak section of the trip.
All meals are provided from Day 2 (Lukla) through Day 18 (Kathmandu farewell dinner). Teahouse meals on the trek include dal bhat, noodles, pasta, soups, porridge, eggs, and local bread. The quality improves significantly in Namche and Dingboche teahouses. At Island Peak Base Camp our kitchen crew prepares hot meals in the mess tent. Water above Namche should be treated, teahouses provide boiled water for a small fee, or we recommend a water purification system. We carry water purification tablets as part of the medical kit. Staying hydrated at altitude is critically important and reduces altitude sickness risk.
October is the single best month: stable post-monsoon weather, excellent visibility, and island Peak in ideal snow conditions. The early October headwall is firm ice, good crampon purchase and minimal avalanche risk. Late September is also excellent. April is the best spring month with warmer temperatures and similar stability. May has strong spring conditions but Everest expedition traffic makes the lower Khumbu trail busier. We avoid June through August, monsoon precipitation makes the Island Peak glacier dangerously soft and unstable.
Yes. Common extensions include adding the Gokyo Lakes loop via Cho La Pass (which would add 4 to 5 days before the Island Peak section), adding a helicopter return from Lukla to save the Namche-to-Lukla descent days, or adding Lobuche East (6,119 m) as a second peak after Island Peak. The itinerary can also be shortened by removing the Nangkartshang acclimatization hike (not recommended) or by using a helicopter to Lukla in both directions. Contact our Kathmandu office before booking to discuss customisation options and revised pricing.
We cap all Island Peak departures at 10 trekkers and climbers. Small groups are critical on Island Peak for two reasons: the summit ridge and headwall create natural bottlenecks, and one-to-one climbing Sherpa support on the headwall requires a manageable party size. Larger operators sometimes run Island Peak with 14 to 16 participants and two climbing Sherpas, this creates queuing and delays at the headwall that extend summit day to dangerous lengths. Our cap of 10 keeps summit day within the safe pre-dawn-to-early-afternoon window.
Our guides carry pulse oximeters and check SpO2 readings every morning above 3,500 m. If a trekker shows signs of serious altitude illness, confusion, ataxia, severe headache that does not respond to descent and medication, we initiate an emergency descent immediately. Our medical kit includes a Gamow bag (portable altitude chamber) available at our Namche base. For helicopter evacuation, our Kathmandu office coordinates directly with the Nepal emergency aviation services. We have pre-authorised contacts and evacuation protocols for the Khumbu that we have used on prior departures. Insurance companies covering helicopter evacuation typically reimburse costs within 30 days of the claim.
The EBC Trek with Island Peak Climbing package starts from USD 2,200 per person, which includes airport transfers, 3 nights in a Kathmandu hotel, Lukla flights, 15 nights of teahouse accommodation, 2 nights of tented camp at Island Peak Base Camp, all meals, all four permits including the Island Peak climbing permit, licensed trekking guide, certified climbing Sherpa for the summit, one porter per two trekkers, all climbing equipment hire, fixed rope installation, first-aid kit with Gamow bag, and government taxes. Travel insurance, international flights, personal gear, and tips are not included.

Amazing experience on Island Peak and EBCBy Elisabetta Ffrom ItalyJune 20, 2026I loved every second of it! Ended up on a solo trip with my excellent guide Binod Banjara from Everest Trekking Company who listened to my needs at all times and helped me when I was in need. I never felt alone but actually found a family. The Island Peak climbing section is challenging but rewarding and so is the EBC trek approach. Highly recommended for anyone considering this combined itinerary!Date of Experience: May 01, 2026

Essential Info for EBC Trek with Island Peak Climbing
This page covers the essential practical information for the EBC Trek with Island Peak Climbing including the technical requirements of the climb, fitness and experience levels needed, climbing permits, group size, and briefing day details at Everest Trekking Company in Kathmandu.
Trek and Climb Difficulty
- This program is rated very challenging. It combines the standard EBC trekking route with a technical summit attempt on Island Peak (Imja Tse) at 6,189m
- Island Peak is classified as a trekking peak by the Nepal Mountaineering Association but the summit involves glacier travel, fixed rope ascending with a jumar, crampons on glaciated terrain, and exposure above 5,800m
- Prior high altitude trekking experience above 4,000m is strongly recommended. A confirmed comfort level with steep and exposed terrain is required
- Summit day begins at approximately 2am to 3am from Island Peak Base Camp (5,100m) and involves 6 to 8 hours of climbing to reach the summit and return to base camp safely
- No prior technical climbing experience is absolutely required for Island Peak but basic rope technique must be learned and practiced at base camp before the summit attempt
- Everest Trekking Company summit certified guides lead the climbing section and make all summit day go or no-go decisions based on SpO2, weather, and individual trekker condition
Group Size and Guide Ratio for the Climbing Section
- Maximum 6 trekkers per Island Peak departure to maintain close guide supervision on the glaciated summit sections
- The ratio on summit day is a maximum of 3 trekkers per climbing guide on the fixed rope sections above base camp
- A base camp manager stays at Island Peak Base Camp during the summit attempt to coordinate logistics and emergency contact with Kathmandu
- Everest Trekking Company carries expedition supplemental oxygen and a Gamow bag to Island Peak Base Camp on every departure
Physical Preparation Guide for the Climbing Section
- Begin preparation 12 to 16 weeks before departure including both cardiovascular training and specific upper body and grip strength work
- Grip strength and arm endurance are important for ascending fixed ropes with a jumar above 5,500m. Include pull ups, rope climbing, and resistance training in your preparation
- Complete at least one multi-day hike of 5 to 6 consecutive days before departure to build the cumulative stamina this 20 plus day itinerary requires
- Train with crampons if at all possible before arrival. Any ski slope, indoor ice wall, or glacier walk experience with crampons significantly improves summit day performance and confidence
Permits Required
- Sagarmatha National Park Entry Permit: NPR 3,000 per person
- TIMS Card: NPR 2,000 per person for organized group trekkers
- Khumbu Pasang Lhamu Rural Municipality Entry Fee: NPR 2,000 per person
- Nepal Mountaineering Association (NMA) Climbing Permit: Required for the peak climb, fee varies by season. Everest Trekking Company arranges this permit on your behalf as part of the package

Packing List for EBC Trek with Island Peak Climbing
Packing the right gear is one of the most important steps in preparing for the EBC Trek with Island Peak Climbing. Too much weight slows you down and adds unnecessary strain at altitude. Too little leaves you cold, wet, or unprepared when conditions change above 4,000m. This packing list is built from years of experience guiding trekkers through the Khumbu region and reflects exactly what Everest Trekking Company recommends every guest to carry. Items in this list are proven on the route and selected for weight, performance, and availability in Kathmandu if you prefer to buy or rent locally.

Travel Note for EBC Trek with Island Peak Climbing
The EBC Trek with Island Peak Climbing is the highest standard program in the Everest Trekking Company portfolio, combining the full Khumbu trekking route with a technical summit attempt on Island Peak (Imja Tse) at 6,189m. This guide covers the specific planning that separates a climbing trip from a standard trek.
What Makes the EBC Trek with Island Peak Climbing Different
- Island Peak (Imja Tse) at 6,189m is classified as a trekking peak by the Nepal Mountaineering Association but involves glacier travel, fixed rope sections, and the use of crampons and an ascender above 5,500m
- A Nepal Mountaineering Association climbing permit is required for Island Peak and is arranged by Everest Trekking Company as part of the trip package
- The climbing section adds a full pre-summit acclimatization rotation from Island Peak Base Camp (5,100m) before the actual summit push, adding 2 to 3 days to the standard EBC schedule
- Summit day on Island Peak begins at approximately 2am to 3am from base camp and reaches the summit typically between 6am and 9am depending on conditions
- The summit crater rim of Island Peak provides a direct view into the Western Cwm of Everest and across to the south faces of Lhotse and Nuptse from 6,189m
- Everest Trekking Company assigns summit certified climbing guides to every Island Peak departure with full expedition medical kits including oxygen and Gamow bags at base camp
- This is the recommended first technical Himalayan climb for trekkers who want to progress beyond standard high altitude trekking
Cultural Highlights on the EBC and Island Peak Route
- Chhukung Valley on the approach to Island Peak Base Camp is one of the most remote and least visited valleys in the Khumbu, surrounded by the south faces of Lhotse, Nuptse, and Ama Dablam
- Tengboche Monastery on the main EBC approach section is the central cultural stop of this combined itinerary
- Island Peak Base Camp at 5,100m is itself a mountaineering landmark, used as the staging point for Everest expeditions in the early years of the sport before higher camps were established
- Lobuche memorial chortens on the Dughla ridge are a powerful and sobering cultural stop connecting the climbing ambition of this itinerary to the human cost of Himalayan mountaineering
- Namche Bazaar acclimatization day includes the Sherpa Culture Museum and the Everest Museum giving essential historical context before the climbing section begins
Things Not to Do on the EBC Trek with Island Peak Climbing
- Do not attempt the Island Peak summit without completing all scheduled acclimatization days including the base camp rotation. The summit push at 6,189m requires the body to be fully adapted and no shortcut exists in the acclimatization schedule
- Do not use the fixed ropes on Island Peak without your Everest Trekking Company guide demonstrating correct ascender technique at base camp the day before the summit attempt
- Do not underestimate the cold at 2am summit departure from Island Peak Base Camp at 5,100m. Your warmest gloves, down jacket, and balaclava are all required and must be ready the night before
- Do not summit without crampons properly fitted and tested. The approach above 5,500m is glaciated and crampons are not optional equipment on this route
- Do not book this itinerary without at least one prior trek above 4,000m. The combined altitude and technical demand is significantly higher than a standard EBC trek
- Do not push for the summit if your guide gives a no-go decision. Everest Trekking Company climbing guides make summit decisions based on your SpO2, weather, and physical state and their decision is final
- Do not ascend more than 300 to 500 meters sleeping altitude per day on the trekking section
- Do not trek or climb without expedition level insurance covering technical climbing rescue above 6,000m
- Do not take sleeping pills at any point on this itinerary above 3,000m

- Book at least 6 to 8 weeks ahead for spring (March to May) and autumn (September to November) as peak season flights sell fast
- Arrive in Kathmandu at least one full day before your Everest Trekking Company pre-trek briefing to recover from long haul travel
Kathmandu to Lukla Domestic Flight
- The Lukla flight takes approximately 35 minutes on small propeller aircraft operated by Tara Air and Summit Air
- In peak spring season (March to May) flights depart from Manthali Airport in Ramechhap, requiring a 4 to 5 hour pre-dawn drive from Kathmandu starting at 2am to 3am
- Outside peak season flights depart from Kathmandu domestic terminal directly
- Luggage allowance on Lukla flights is 15kg checked plus 5kg carry on
- Flights are weather dependent. Everest Trekking Company monitors schedules and builds buffer days into all itineraries
Porter Weight Limits and Day Pack Guide
- Your Everest Trekking Company porter carries your main bag at a maximum of 20kg including the bag weight
- You carry your own day pack (5 to 8kg): water, snacks, rain jacket, camera, headlamp, sunscreen, medication, one warm layer
- All ETC porters receive proper trekking gear, rain equipment, warm jackets, and altitude insurance coverage
- Recommended porter tip: USD 8 to 10 per day, paid in cash at the end of the trek
Free Luggage Storage at Everest Trekking Company Office
- Leave your city clothes, laptop, extra shoes, and anything not needed on the trail at our Kathmandu office at no charge
- Your bags are stored securely and ready for collection on your return from the mountains
- Pack your trek bag and storage bag separately at home so handover on briefing day is quick
- Full storage instructions are given during your pre-trek briefing day in Kathmandu
Money, ATMs and Daily Budget
- ATMs available in Kathmandu (Thamel) and Namche Bazaar (3,440m) only before the high route
- Carry sufficient Nepali Rupees in cash from Namche upward. Most tea houses above Phakding do not accept cards
- Budget NPR 3,500 to 5,000 per day above Namche for accommodation, three meals, and incidentals
- Hot showers: NPR 200 to 500 extra. Wifi: NPR 200 to 500 per hour. Device charging: NPR 100 to 300 above Namche
- Lead guide tip recommendation: USD 15 to 20 per day paid in cash at trek end
Connectivity and SIM Cards
- Buy an Ncell SIM at Kathmandu airport or in Thamel. Bring your passport to register it
- 4G data works well in Kathmandu, Lukla, Namche, and Dingboche. Signal becomes patchy above Dingboche
- Download offline maps on Maps.me or Gaia GPS before leaving Kathmandu
- Tea house wifi above Namche is slow and charged separately. At Gorakshep it is satellite only and very unreliable
- Everest Trekking Company guides carry satellite phones and maintain daily contact with Kathmandu base operations
Altitude Sickness
The EBC Trek with Island Peak Climbing reaches the highest elevation of any standard Everest Trekking Company program. Island Peak, also known as Imja Tse, stands at 6,189m, and the summit attempt follows a night at Island Peak Base Camp at approximately 5,100m. Altitude sickness on this route is not just a trekking concern but a climbing safety factor, because symptoms that are manageable at base camp can escalate rapidly during a technical summit push above 6,000m. Everest Trekking Company assigns summit-certified high altitude guides to every Island Peak departure and carries expedition-grade medical kits including Gamow bags to base camp.
What Everest Trekking Company Guides Always Carry for Altitude Safety
- Portable oxygen cylinder: Every Everest Trekking Company guide carries supplemental oxygen above 4,000m and knows exactly when and how to administer it
- Calibrated pulse oximeter (SpO2 monitor): Used to measure blood oxygen saturation at every major stop and every morning and evening camp check
- Complete first aid kit: Stocked with altitude medicines, wound care, blister treatment, antiseptic, bandages, and emergency essentials
- Diamox (Acetazolamide): Carried for both prevention and treatment of acute mountain sickness and dispensed under guide supervision when indicated
- Dexamethasone: Emergency steroid for severe High Altitude Cerebral Edema (HACE), administered while rescue is being arranged
- Nifedipine: Emergency medication for High Altitude Pulmonary Edema (HAPE), reduces lung vessel pressure rapidly
- Gamow bag (portable altitude chamber): Available through Everest Trekking Company logistics network at key high altitude points, simulates a descent of 1,500m when helicopter rescue is delayed
- Satellite phone and radio: For direct contact with Everest Trekking Company Kathmandu base operations and certified helicopter rescue teams at any point on the route
What is Altitude Sickness?
- Altitude sickness, also called Acute Mountain Sickness (AMS), is the body’s reaction to reduced oxygen levels at high elevation
- At sea level, air contains about 21 percent oxygen at normal atmospheric pressure
- As you gain elevation, air pressure drops and each breath delivers less oxygen to your blood and organs
- At 3,440m (Namche Bazaar), oxygen availability is roughly 67 percent of what it is at sea level
- At 5,364m (Everest Base Camp), each breath delivers only about 50 percent of the oxygen you would get at sea level
- The human body needs time to produce more red blood cells and adapt to this lower oxygen environment
- When you ascend faster than your body can adjust, altitude sickness occurs
- Anyone can get altitude sickness regardless of fitness level, age, or previous trekking experience
- Being physically fit does not protect you from altitude sickness and does not speed up acclimatization
- Experienced trekkers who have had no issues before can be affected on a new trip
Why Does Altitude Sickness Happen?
- Lower air pressure at altitude means less oxygen enters the lungs with each breath
- Your blood carries less oxygen to vital organs including the brain, heart, and muscles
- The brain is particularly sensitive to reduced oxygen
- When oxygen levels drop too fast, blood vessels in the brain can leak fluid, causing swelling inside the skull
- Fluid can also build up inside the lungs in more severe cases, a condition called HAPE
- The body responds by breathing faster and increasing heart rate trying to compensate for the lower oxygen
- This compensation process takes days and sometimes up to two weeks to fully complete at each new altitude
- Dehydration at altitude makes the situation worse because blood becomes thicker and circulates less efficiently
- Cold, dry mountain air causes faster fluid loss through breathing than you would expect
- Poor sleep at altitude also slows the acclimatization process, which is why nights are often the hardest time
- Alcohol, strong sedatives, and sleeping pills suppress breathing and reduce blood oxygen during sleep, making acclimatization slower
When Does Altitude Sickness Start?
- Mild symptoms can begin as low as 2,500m in some people
- Most trekkers first notice symptoms around Namche Bazaar at 3,440m, usually on the evening of arrival or the following morning
- Symptoms typically appear 6 to 12 hours after arriving at a new elevation
- Symptoms often feel worse during the night and early morning hours when breathing naturally slows during sleep
- The risk increases significantly above 4,000m
- Dingboche at 4,360m and Lobuche at 4,940m are the zones where moderate to severe AMS becomes most likely on the EBC route
- On the standard itinerary, the greatest risk nights are those spent at Dingboche, Lobuche, and Gorakshep
- Even trekkers with no previous history of AMS can be affected on any given trip
- Speed of ascent is the most important factor. The faster you go up, the higher your risk
- People who have had AMS before are not necessarily more at risk, and those who have never had it are not necessarily protected
Altitude Risk Points on the EBC Trek with Island Peak Climbing
- Namche Bazaar (3,440m): Acclimatization base for both the EBC trek and the Island Peak climbing preparation
- Dingboche (4,360m): Extended rest day here is built into the Island Peak climbing schedule and is key to readiness above 5,000m
- Chhukung (4,730m): Side camp used for high altitude adjustment before Island Peak Base Camp
- Island Peak Base Camp (approximately 5,100m): Pre-summit overnight, rest quality here directly affects climbing safety and summit success the following day
- Island Peak Summit (6,189m): Highest point of any standard ETC program, technical summit with glacier travel and fixed ropes above 5,800m
- At 6,189m the risk of HACE and HAPE is real and requires immediate recognition from every member of the team
- Lobuche (4,940m) and Gorakshep (5,140m): Standard EBC high risk nights still apply on this combined route after the Island Peak summit
- Everest Trekking Company carries emergency supplemental oxygen and a Gamow bag to Island Peak Base Camp on every departure
Symptoms of Altitude Sickness: Mild AMS
- Headache, often described as a dull pressure at the front or sides of the head
- Fatigue and general tiredness not explained by the day’s walking distance or effort
- Loss of appetite, especially for heavy or oily foods
- Nausea, sometimes with mild vomiting in the evenings
- Difficulty sleeping or very light, broken sleep with frequent waking
- Dizziness when standing up or changing position quickly
- Slight shortness of breath after minor exertion such as walking up stairs or a short slope
- A feeling of general unwellness that is hard to describe specifically
- Mild swelling of fingers noticed when removing rings or tightening watch straps
Symptoms of Altitude Sickness: Moderate AMS
- Persistent and worsening headache that does not improve with paracetamol or ibuprofen
- Significant nausea and repeated vomiting making it hard to keep fluids or medication down
- Severe fatigue where basic tasks like getting dressed or walking to the toilet feel exhausting
- Difficulty walking in a straight line, similar to the feeling of being off balance
- Shortness of breath that occurs even at rest, not just during activity
- Reduced urine output and noticeably dark yellow urine despite drinking fluids
- Visible swelling of the face, hands, or feet
- Dry cough that becomes more persistent through the day and night
- Inability to concentrate or follow simple conversation
- A worsening score on the Lake Louise AMS Assessment used by our guides
Symptoms of Altitude Sickness: Severe AMS, HACE and HAPE
- High Altitude Cerebral Edema (HACE) is swelling of the brain caused by fluid leaking from blood vessels at extreme altitude
- HACE symptoms include severe confusion, disorientation, and irrational behavior
- Loss of coordination and inability to walk without support are key warning signs of HACE
- Slurred speech and extreme drowsiness are serious signs that demand immediate action
- Severe headache that does not reduce with any medication is a red flag for HACE
- Loss of consciousness can occur in advanced cases if descent is delayed
- High Altitude Pulmonary Edema (HAPE) is the buildup of fluid inside the lungs and is the leading cause of death from altitude sickness
- HAPE symptoms begin with a persistent dry cough that progresses to producing pink or frothy mucus
- Extreme breathlessness even when lying still is the hallmark symptom of HAPE
- A crackling or gurgling sound can sometimes be heard in the chest when breathing
- Rapid heart rate, blue lips, and blue fingertips (cyanosis) indicate dangerous oxygen deprivation from HAPE
- Both HACE and HAPE require immediate descent of at least 500 to 1,000 meters along with emergency medication
How to Prevent Altitude Sickness
- Ascend slowly. Never gain more than 300 to 500 meters of sleeping altitude per day above 3,000m
- Follow the climb high, sleep low rule. Hike higher during the day but return to lower elevation to sleep
- Take all acclimatization rest days on your itinerary seriously. The ETC itinerary includes mandatory rest days at Namche and Dingboche for this reason
- Stay well hydrated. Drink 3 to 4 liters of clean water per day throughout the trek, more on heavy walking days
- Avoid alcohol during the first 2 to 3 days at each new altitude zone
- Avoid sleeping pills and strong sedatives above 3,000m as they suppress breathing during sleep
- Eat well even when your appetite is low. Small, frequent meals are easier to manage than large ones
- Avoid flying directly to high altitude without a gradual approach schedule
- Monitor urine color throughout the day. Pale yellow means you are well hydrated. Dark yellow means drink more
- Walk at a slow, steady pace. You should be able to hold a normal conversation while trekking without getting out of breath
- Rest as soon as you feel any symptoms rather than pushing on hoping they will pass
Medication for Altitude Sickness Prevention and Treatment
- Diamox (Acetazolamide) is the most widely used medication for altitude sickness prevention
- It works by stimulating faster and deeper breathing, which increases blood oxygen levels throughout the day and night
- Standard preventive dose is 125mg to 250mg twice daily, starting 24 hours before ascending to a new high altitude zone
- Common side effects include tingling in the fingers and toes, increased urination, and a strange taste with carbonated drinks
- Diamox is a sulfa family drug and must be avoided by anyone with sulfa drug allergy or aspirin sensitivity
- Always consult a doctor before starting Diamox as it requires a prescription in most countries
- Diamox does not mask symptoms. It genuinely helps the body acclimatize faster, unlike pain medication alone
- Ibuprofen 400mg every 8 hours has been shown in multiple clinical studies to reduce both headache and mild AMS severity
- Dexamethasone is a steroid used for emergency treatment of severe HACE and reduces brain swelling rapidly but is not a substitute for descent
- Nifedipine is used in emergency treatment of HAPE and reduces blood pressure in the lung vessels
- Everest Trekking Company guides carry Diamox, Dexamethasone, and Nifedipine on every trek above 3,000m
How Everest Trekking Company Monitors and Manages Altitude Sickness
- Every Everest Trekking Company guide is trained and certified in Wilderness First Aid including altitude illness management protocols
- All guides carry calibrated pulse oximeters to measure blood oxygen saturation (SpO2) at every stop and campsite
- A reading above 90 percent SpO2 is generally acceptable. A reading below 85 percent triggers immediate evaluation and action
- We carry emergency Diamox, Dexamethasone, Nifedipine, and supplemental oxygen cylinders in the first aid kit on every trek
- Portable altitude chambers (Gamow bags) are available through our logistics network at key high altitude points
- Every guest is given a full briefing on AMS symptoms, warning signs, and our response plan on day one before the trek begins
- We run a formal health check and SpO2 assessment at Namche Bazaar and again at Dingboche
- Our itinerary is built with safety buffer days so no trekker is ever pressured to push on when they are not feeling well
- Guides check SpO2 readings of every trekker each morning and evening and record the results
- Any reading that drops 10 or more percent compared to a trekker’s baseline triggers immediate investigation and close monitoring
- We use the Lake Louise Scoring System to objectively assess AMS severity rather than relying only on trekker self-reporting
- Guests showing even mild symptoms receive reduced activity, extra rest, increased fluids, and hourly monitoring
- No trekker is allowed to ascend further if they have a moderate or severe AMS score until the guide is satisfied they have recovered fully
Rescue Process When Altitude Sickness Becomes Serious
- If a trekker cannot descend safely on foot, our guide contacts Everest Trekking Company base operations in Kathmandu immediately via satellite phone or radio
- We work with certified helicopter rescue operators based in Lukla and Kathmandu with proven experience in high altitude rescue
- Rescue helicopters can reach most points on the EBC route within 30 to 90 minutes depending on weather and light conditions
- Our team contacts the helicopter company directly to avoid any delay in communication or response
- The helicopter lands at the nearest safe landing zone such as Pheriche, Dingboche, Namche, or Lobuche depending on where the guest is located
- While waiting for the helicopter, the guide administers emergency medication, Dexamethasone for HACE or Nifedipine for HAPE
- Supplemental oxygen is administered immediately if available from the local lodge or our kit
- If the helicopter is delayed more than 20 minutes and conditions are severe, the Gamow bag is inflated and the trekker placed inside
- A Gamow bag simulates a descent of approximately 1,500 meters by increasing the air pressure inside the sealed bag, giving immediate relief
- The trekker is kept warm, monitored continuously, and given small sips of fluid if conscious and able to swallow safely
- A guide or porter accompanies the trekker to the helicopter and if possible all the way to the hospital in Kathmandu
- Our Kathmandu operations team meets the helicopter and coordinates handover to hospital medical staff
- Full health records from the trek including SpO2 logs, symptom timeline, and medications given are provided to the hospital team
- Everest Trekking Company contacts the trekker’s emergency contact and travel insurance company as soon as evacuation is confirmed
- We assist with all insurance documentation and stay in contact with the trekker and their family through the full recovery process
Travel Insurance and Financial Preparation for Altitude Rescue
- Every trekker joining an Everest Trekking Company trip is required to carry travel insurance that covers helicopter evacuation above 5,000m
- Rescue helicopter flights typically cost between USD 3,000 and USD 6,000 per flight depending on the pick up location and operator
- Hospital treatment costs in Kathmandu vary depending on the severity of the illness and length of stay
- Our team helps coordinate insurance claims and provides all documentation required by the insurer
- Never attempt the Everest region without verified helicopter evacuation cover in your travel insurance policy
- Check that your policy specifically states coverage above 5,000m as many standard adventure policies have elevation limits of 4,000m or 4,500m
- Save your insurance policy number and the insurer’s 24 hour emergency number in your phone before the trek begins
- Everest Trekking Company can recommend verified travel insurance providers if you need guidance before booking your trek
