Cho La, at 5,420 meters, is the middle pass of the Everest Three Passes Trek and, of the three, the one most defined by its glacier: reaching the pass means crossing a genuinely icy, crevasse-scarred glacier on its western approach, making Cho La the most technically involved crossing on the circuit even though it is not a full mountaineering objective. The pass connects Dzongla, at around 4,830 meters on the Everest Base Camp side of the route, with Thagnak, at roughly 4,700 meters on the Gokyo side, giving trekkers a direct link between the two most iconic valleys in the Khumbu without a long detour back down to Namche Bazaar.
This guide covers what actually makes Cho La difficult, the glacier crossing itself and what equipment it requires, how it fits into a Three Passes or combined Everest Base Camp and Gokyo itinerary, and the acclimatization, timing, and safety considerations that matter most for a crossing that snow covers for roughly nine months of the year.
Where Cho La Is and What It Connects
Cho La sits on the ridge between the Chola valley below Dzongla and the Ngozumpa Glacier side near Thagnak, making it the connecting link between the Everest Base Camp trail and the Gokyo Lakes valley. Trekkers doing a combined Everest Base Camp and Gokyo Lakes trip, or the full Three Passes circuit, typically cross Cho La either after visiting Everest Base Camp and Kala Patthar and before continuing on to Gokyo, or in the reverse direction after Gokyo on the way toward Base Camp.
The Cho La Glacier Crossing
What sets Cho La apart from Renjo La and gives it a reputation as the more serious of the two lower passes is the glacier on its western side, a stretch of permanent ice and snow that, depending on the season and recent weather, can require crampons or at minimum sturdy microspikes to cross safely. The glacier’s edge is unstable, and the route across it shifts somewhat from season to season as the ice moves and crevasses open and close, which is one reason a guide with current, first-hand knowledge of the crossing matters more here than on Renjo La’s more static, non-glaciated trail.
Snow covers Cho La for roughly nine months of the year, and even in the main spring and autumn trekking seasons, overnight refreeze can leave the glacier surface hard and slick by the time trekkers cross in the early morning, which is exactly when most guides schedule the crossing, both to take advantage of firmer, more predictable snow conditions and to finish before afternoon weather moves in.
How Difficult Is Cho La Compared to Renjo La and Kongma La
Of the three passes on the Everest Three Passes circuit, Cho La is generally considered the second hardest, harder than Renjo La because of the glacier crossing and the crampon or microspike requirement, but somewhat less brutal underfoot than Kongma La, whose steep, loose boulder descent on the Chukhung side is notoriously hard on the knees. Cho La’s difficulty is concentrated specifically in the glacier section; the approach from Dzongla and the descent toward Thagnak are demanding high-altitude trekking but not technically different from other sections of trail in the region.
What makes Cho La feel more serious than Renjo La to most trekkers is less the sustained difficulty of the whole day and more the specific, focused challenge of the glacier itself: loose rock and scree on the approach, then a transition onto ice and snow where a slip has real consequences given the crevasses and the glacier’s unstable edge. A guide who crosses regularly will typically rope up the group for the glacier section in less stable conditions, or at minimum walk the line personally to check the safest route before bringing clients across.
Best Season to Cross Cho La
Autumn, from late September through November, and spring, from March through May, are the two recommended windows for Cho La, matching the pattern for the wider Everest region. Autumn generally offers more settled weather immediately after the monsoon clears, giving guides a clearer read on current glacier and snow conditions, while spring brings slightly milder daytime temperatures but a higher chance of afternoon cloud as the pre-monsoon pattern develops.
Winter crossings of Cho La are considerably more serious than in the main seasons, since heavier and more persistent snow cover can obscure crevasses and make the glacier crossing meaningfully more hazardous, and only experienced, well-equipped parties with a guide who knows current conditions should consider it. The monsoon season from June through August should be avoided entirely; poor visibility removes any safety margin on the glacier, and wet snow conditions increase the risk of a slip or a hidden crevasse becoming a real hazard.
Gear Needed for the Cho La Glacier Crossing
Beyond the standard high-altitude trekking kit of warm layers, a good down jacket, and sturdy trekking boots, Cho La specifically calls for microspikes or, in icier conditions, full crampons, along with trekking poles for stability on the approach and descent. A guide experienced on this route will assess current glacier conditions and advise on exactly what traction equipment is needed for your specific crossing date, since conditions vary meaningfully from a firm, well-trodden trail in peak season to a more technical, icy surface after a cold snap or fresh snowfall.
Some operators also carry a short length of rope for the group to use across the more exposed sections of the glacier in marginal conditions, along with a basic ice axe for the guide, even though clients themselves rarely need to carry one on the standard route. Sunglasses or glacier goggles with strong ultraviolet protection are essential, since sunlight reflecting off the glacier surface is intense and prolonged exposure without eye protection carries a real risk of snow blindness.
Standard Itinerary for Crossing Cho La
Cho La is almost always crossed as part of a longer itinerary that combines Everest Base Camp with the Gokyo Lakes, or as part of the full Three Passes circuit, rather than as a standalone objective, since reaching either Dzongla or Thagnak already requires a week or more of trekking and acclimatization from Lukla. In the most common direction, trekkers complete the standard Everest Base Camp and Kala Patthar itinerary first, then head from Dzongla, a small settlement just off the main trail near Dingboche, across Cho La to Thagnak and on to Gokyo, rather than retracing the entire Base Camp trail back to Namche.
A typical combined itinerary runs 16 to 19 days from Kathmandu to Kathmandu, with acclimatization days built in around Namche Bazaar and again around Dingboche or Chukhung before the push to Everest Base Camp, a rest day at Dzongla or nearby before the Cho La crossing itself, and a further acclimatization day around Gokyo afterward, often including the Gokyo Ri climb, before continuing on to Renjo La if the itinerary is the full Three Passes circuit or heading back down through Namche if it is a combined Base Camp and Gokyo trip without the third pass.
Acclimatization Before Cho La
Because Cho La is usually crossed after Everest Base Camp and Kala Patthar, most trekkers arrive at Dzongla already reasonably well acclimatized to altitudes above 5,000 meters, which is one practical advantage of this common itinerary direction. Even so, the crossing itself, combined with the technical demands of the glacier, means a rested, well-hydrated start matters, and guides typically prefer trekkers spend a night at Dzongla rather than pushing straight through from Lobuche or Gorak Shep on the same day as the crossing.
Trekkers attempting Cho La in the opposite direction, from Thagnak toward Dzongla, generally do so after time spent acclimatizing around Gokyo, including the Gokyo Ri climb, which serves a similar purpose in preparing the body for the altitude of the pass itself. Either direction, watch for the standard warning signs of altitude illness, headache, nausea, unusual fatigue, and poor sleep, in the days before the crossing, and be prepared to delay if symptoms have not resolved.
Cho La’s Role in the Everest Three Passes Trek
For trekkers completing the full Everest Three Passes circuit, Cho La is the connective link between Kongma La on the Everest Base Camp and Chukhung side and Renjo La on the Gokyo side, making it geographically and logistically the middle pass of the three regardless of which direction the loop is walked. Our comprehensive guide to the Three Passes Trek in Nepal covers how all three passes fit together, typical itinerary lengths, and the cumulative fitness and acclimatization demands of crossing all three rather than tackling any one in isolation.
Trekkers who want the glacier-crossing experience and the connection between Everest Base Camp and Gokyo without adding Kongma La to the itinerary often choose a combined Everest Base Camp, Cho La, and Gokyo Lakes trek instead, which delivers two of the three passes and both of the region’s signature valleys in a somewhat shorter and less demanding itinerary than the full circuit.
Guides and Safety on the Cho La Glacier
A guide with genuine, current experience on the Cho La glacier is arguably more important here than on either of the other two passes, given how much the crossing’s difficulty depends on snow and ice conditions that change from week to week. An experienced guide will scout the current line across the glacier, know whether crampons or microspikes are needed on a given day, and make the call on whether to rope the group up for the more exposed or crevassed sections, decisions that require real local knowledge rather than a generic guiding qualification.
Our broader Everest Base Camp trek safety guide covers altitude, weather, and evacuation considerations that apply across the whole region including Cho La, and the same core principles, honest symptom reporting, a guide willing to delay or turn back when conditions warrant it, and confirmed insurance coverage before you go, matter here as much as anywhere on the Three Passes circuit. Given the glacier crossing specifically, travel insurance should explicitly cover trekking on glaciated terrain in addition to the standard altitude and helicopter evacuation coverage; our travel insurance guide for the Everest Base Camp trek explains what to check for before booking.
What Happens If Cho La Is Unsafe to Cross
Reputable operators build a buffer day into Cho La itineraries specifically because glacier conditions can occasionally make the standard route temporarily unsafe, whether due to fresh snowfall obscuring crevasses, high wind, or poor visibility. When this happens, a guide’s options are to wait a day at Dzongla or Thagnak for conditions to improve, or in some cases to retrace the route back the way the group came, rejoining the main trail rather than attempting a crossing in marginal conditions.
This is one of the strongest arguments for choosing an itinerary with at least one contingency day around the Cho La crossing rather than a tightly scheduled trip with no room for a weather delay, since a guide under pressure to keep a rigid schedule is more likely to make a riskier call than one with the flexibility to simply wait for a better day.
Fitness and Training for Cho La
Preparing for Cho La means preparing for a demanding high-altitude trekking day with a technical glacier section, so training should combine the sustained cardiovascular conditioning needed for any high-altitude Himalayan trek with some basic comfort moving in crampons or microspikes if you have the chance to practice beforehand. Our detailed training guide for the Everest Base Camp trek lays out a structured preparation plan that applies directly to a Cho La itinerary, and trekkers with any prior experience on snow or ice, even a guided winter hike or a session at a climbing gym with crampon practice, will find the glacier crossing considerably less intimidating.
Because Cho La is usually crossed partway through a longer Everest Base Camp and Gokyo itinerary, by which point trekkers have already covered a week or more of high-altitude trekking, cumulative fatigue is a real factor to train for as well, not just the difficulty of a single day in isolation. Building endurance for multiple consecutive demanding days, rather than just peak fitness for one hard day, is what actually prepares you well for this stage of the trip.
Cost of a Combined Everest Base Camp, Cho La and Gokyo Trek
A combined itinerary that includes Everest Base Camp, the Cho La crossing, and the Gokyo Lakes typically runs somewhat more than the standard out-and-back Everest Base Camp trek simply due to the additional days involved, generally in the range of what our published Everest Base Camp trek cost guide outlines, scaled up for the extra week or so the Gokyo extension adds. Expect the same categories of cost as the standard trek, permits, Lukla flights, teahouse accommodation and meals, and guide and porter fees, with no additional special permit required specifically for the Cho La crossing itself beyond the standard Sagarmatha National Park and rural municipality fees.
The full Three Passes circuit, adding Kongma La and Renjo La on top of Cho La, extends the trip further still, typically to 18 to 21 days, and costs proportionally more due to the additional guiding and accommodation days rather than any special permit or fee tied to the passes themselves.
Dzongla and Thagnak: The Villages on Either Side
Dzongla is a small, high-altitude settlement just off the main Everest Base Camp trail near Dingboche, consisting of a handful of basic teahouses that exist primarily to support trekkers heading toward or coming from Cho La, and it has a noticeably quieter, more remote feel than the busier stops along the main Base Camp route. Thagnak, on the Gokyo side, is similarly small and serves the same function for trekkers approaching Cho La from the Gokyo direction, sitting close to the Ngozumpa Glacier, Nepal’s largest, which trekkers get a striking close-up view of on the approach.
Both villages have limited services compared to Namche Bazaar or even Gokyo itself, so trekkers should not expect the range of food options, shops, or communication facilities found at the more established stops along the main trail, and should plan accordingly for a simpler overnight before and after the crossing.
Do I need a guide to cross Cho La
Yes, unequivocally. The glacier crossing, the unstable edge conditions, and the remote, unmarked nature of parts of the route make Cho La a poor choice to attempt independently even for experienced trekkers, and most operators and past trekkers strongly discourage it. A guide’s ability to read current glacier conditions and choose a safe line across the ice is not something a map or a guidebook description can substitute for.
How long does the Cho La crossing take
Most groups take between six and eight hours for the full crossing from Dzongla to Thagnak or the reverse, including the glacier section itself, though this varies with pace, snow conditions, and how much time the group spends fitting crampons or navigating the trickier sections of ice. As with the other passes, an early start is standard practice, both to take advantage of firmer morning snow conditions and to ensure the group is off the exposed high section well before any afternoon weather develops.
The View From Cho La
While Cho La does not offer quite the same sweeping, open panorama as Renjo La, the view from the pass is still genuinely spectacular, taking in Cholatse and Ama Dablam to the south and a close, dramatic look at the peaks surrounding the Gokyo and Ngozumpa Glacier system to the west. What makes the Cho La crossing memorable is less a single iconic viewpoint and more the experience of the glacier itself, the sense of genuine high-mountain travel that walking across ice between two dramatic rock walls provides, a different kind of reward than the postcard panorama at Renjo La or Kala Patthar.
Weather permitting, the descent toward Thagnak also offers striking views down onto the Ngozumpa Glacier, giving a sense of scale for Nepal’s largest glacier that is hard to appreciate from photographs alone, since the glacier’s debris-covered surface stretches for many kilometers below the trail.
Environmental Considerations on the Cho La Route
The high-altitude terrain around Dzongla, the Cho La glacier itself, and the approach to Thagnak are ecologically fragile and see less traffic than the main Everest Base Camp trail, which means the environmental impact of each trekking group matters more, not less. Pack out all non-biodegradable waste, since there is essentially no capacity for these remote, high-altitude stops to manage litter, and be mindful that the glacier environment itself is sensitive to disturbance in ways that are easy to overlook when focused on the physical challenge of the crossing.
Responsible operators brief clients on minimizing impact specifically around the glacier crossing and the sparse settlements at Dzongla and Thagnak, where the usual redundancy of teahouses and waste management found in busier villages simply does not exist, making individual trekker behavior a bigger factor in the overall environmental footprint of the trek.
Common Mistakes When Planning a Cho La Crossing
The most common mistake is underestimating the technical seriousness of the glacier section based on Cho La’s relatively modest altitude compared with some other parts of the trek; trekkers sometimes assume that because they have already handled Kala Patthar or Everest Base Camp itself, the glacier crossing will be straightforward, when in fact it demands a different kind of attention and appropriate footwear traction that the rest of the standard trek does not require.
A second common mistake is not building a weather or conditions buffer day into the itinerary around the Cho La crossing, leaving no flexibility if the glacier is deemed unsafe on the scheduled day. A third is choosing an operator without specific, current experience on this exact crossing; general Everest Base Camp guiding experience does not automatically translate into the specialized judgment needed to read glacier conditions safely, and this is one part of the Three Passes circuit where that specific experience genuinely matters.
Is Cho La harder than Kala Patthar
Yes, in terms of technical difficulty, though Kala Patthar at roughly 5,545 meters is actually slightly higher in elevation than Cho La’s 5,420 meters. Kala Patthar is a well-trodden out-and-back trail with no glacier crossing and teahouses close by throughout, while Cho La demands crampons or microspikes on genuinely icy, crevassed terrain and connects two remote, sparsely served villages, making it a meaningfully more serious undertaking despite the lower summit altitude.
Can I skip Cho La and still see both Everest Base Camp and Gokyo
Yes, trekkers who prefer not to attempt the glacier crossing can still visit both the Everest Base Camp trail and the Gokyo Lakes by returning to Namche Bazaar after Base Camp and heading up the Gokyo side valley separately, rather than crossing directly via Cho La. This adds a few extra days of walking back down and up through the lower valley but avoids the technical glacier crossing entirely, which is a reasonable choice for trekkers who want to see both areas without the added risk and equipment requirements of Cho La.
What time of day is best to cross Cho La
Early morning is standard practice, both because the glacier surface is typically firmer and more predictable after an overnight refreeze, and because starting early gives the group the best chance of finishing the crossing before any afternoon cloud or wind develops. Most itineraries have trekkers leaving Dzongla or Thagnak well before sunrise or very shortly after, aiming to be across the most exposed sections of the glacier by mid-morning.
Weather and Temperature at Cho La
Given that snow covers the pass for roughly nine months of the year, cold is a constant factor at Cho La even during the main trekking seasons, and overnight temperatures at Dzongla and Thagnak regularly fall well below freezing in spring and autumn. Daytime temperatures at the pass itself, even in direct sun, often remain close to or below freezing, and wind exposure on the glacier can make conditions feel considerably colder than the air temperature alone would suggest.
Checking recent conditions reports from your operator in the days before a scheduled Cho La crossing is worth doing, since glacier and snow conditions can shift meaningfully after a cold snap or fresh snowfall in a way that a general seasonal forecast does not fully capture.
Sample Day-by-Day Structure Around Cho La
A representative itinerary that includes Cho La follows the standard Everest Base Camp trek through Phakding, Namche Bazaar with an acclimatization day, Tengboche, Dingboche with a second acclimatization day, and on through Lobuche to Gorak Shep, with the side trips to Everest Base Camp and Kala Patthar included as usual. Rather than retracing this route back to Namche, the itinerary then routes back down slightly to Dzongla, where trekkers typically spend a night before the Cho La crossing.
From Dzongla, the crossing day leads across the pass and down into Thagnak, followed by a short walk on to Gokyo village itself, where most itineraries build in an acclimatization day that often includes the Gokyo Ri climb. From Gokyo, trekkers either descend back through the Gokyo valley to Namche and Lukla if the trip ends there, or continue on to Renjo La if the itinerary is the full Three Passes circuit. A well-paced version of this combined route runs 17 to 19 days from Kathmandu to Kathmandu for the Base Camp, Cho La, and Gokyo combination, or 19 to 21 days for the full circuit including Kongma La and Renjo La as well.
Health and Altitude Safety Specific to Cho La
Because Cho La is typically crossed after time already spent above 5,000 meters at Everest Base Camp and Kala Patthar, altitude illness risk at the pass itself is often somewhat lower than at earlier points in a typical itinerary, provided the standard acclimatization schedule has been followed properly. That said, the physical exertion of the glacier crossing, combined with cold exposure and the cumulative fatigue of a week or more of high-altitude trekking, means trekkers should not assume they are automatically fine simply because they handled Everest Base Camp without issue.
Watch for persistent or worsening headache, nausea, unusual breathlessness, or confusion in the days around the crossing, and communicate openly with your guide about how you are feeling. A guide experienced on this route will factor in not just altitude symptoms but general fatigue and cold tolerance when deciding whether a client is ready for the technical demands of the glacier crossing on a given day.
What permits are needed for Cho La
The same two permits required for the standard Everest Base Camp trek, the Sagarmatha National Park entry permit and the Khumbu Pasang Lhamu Rural Municipality entry permit, cover the Cho La crossing as well, since the pass sits within the same protected area boundaries. No separate special permit is needed specifically for Cho La itself, unlike the NMA climbing permits required for trekking peaks such as Mera Peak or Island Peak.
Is Cho La suitable for a first-time high-altitude trekker
Cho La is a more demanding undertaking than the standard Everest Base Camp trek alone, given the glacier crossing and technical equipment involved, so it is generally better suited to trekkers who either have some prior high-altitude experience or are completing it as part of a longer itinerary that has already included substantial acclimatization time at Everest Base Camp. First-time high-altitude trekkers who are fit, well-prepared, and traveling with an experienced guide can and do complete Cho La successfully, but it is a bigger step up in difficulty than Everest Base Camp alone.
Choosing the Right Operator for a Cho La Crossing
Given how much the safety and enjoyment of a Cho La crossing depends on current glacier conditions and specific route knowledge, choosing an operator with genuine, recent experience on this exact crossing matters more than it does for many other sections of Everest region trekking. Ask directly how recently the company has guided the crossing, what traction equipment they typically supply or expect clients to bring, and how they handle a scenario where conditions look marginal on the scheduled crossing day.
Operators who treat Cho La as a routine add-on without dedicated attention to current conditions, or who do not build in a weather buffer day, are taking on more risk than the crossing warrants. A company that can speak specifically and confidently about recent Cho La conditions, rather than giving a generic answer about the Everest region more broadly, is a good sign that they take this particular section of the route seriously.
Combining Cho La With a Full Region Experience
For trekkers with the time and fitness for it, combining Cho La with both Everest Base Camp and the Gokyo Lakes, or extending further into the full Three Passes circuit with Kongma La and Renjo La as well, delivers a genuinely comprehensive experience of the Khumbu that a standard out-and-back Everest Base Camp trek does not match. Our guide to choosing the right Everest trek for your goals and experience level walks through how a standard Base Camp trek, a combined Base Camp and Gokyo itinerary, and the full Three Passes circuit compare, which is a useful starting point if you are deciding how ambitious to make this trip.
Trekkers drawn specifically to Gokyo and Renjo La but less interested in the technical glacier crossing at Cho La can also approach the region from the Gokyo side directly, via Namche and the Gokyo valley, without routing through Cho La or Everest Base Camp at all, an option covered in our dedicated Gokyo Lakes trek guide.
How does the Ngozumpa Glacier relate to the Cho La crossing
The Ngozumpa Glacier, Nepal’s largest, runs along the Gokyo valley and is a different, much larger glacier system than the smaller glacier crossed directly at the Cho La pass itself, though the approach to Thagnak from Cho La runs close enough to offer striking views of it. Trekkers sometimes confuse the two; the Cho La crossing itself is a shorter, higher glacier traverse near the pass, while the Ngozumpa is the larger debris-covered glacier visible from the trail on the Gokyo side.
Plan Your Everest Base Camp, Cho La and Gokyo Trek
Cho La is the technical heart of the Everest Three Passes circuit, a genuinely memorable glacier crossing that links two of the region’s most iconic valleys and rewards trekkers who arrive properly prepared, well-acclimatized, and with a guide who knows current conditions on this specific route. It is not a crossing to underestimate, but with the right itinerary, equipment, and operator, it is well within reach for fit, determined trekkers who have already built solid high-altitude experience earlier in the trip.
If a combined Everest Base Camp, Cho La, and Gokyo Lakes itinerary, or the full Three Passes circuit, sounds like the right challenge for your next trip to Nepal, get in touch and we can put together a properly paced route with the acclimatization days, experienced glacier-crossing guidance, and weather flexibility that give you the best realistic chance of crossing safely and enjoying every part of the journey.
Packing List for the Cho La Crossing
Beyond the general high-altitude trekking gear covered in our standard Everest Base Camp trek packing list, a Cho La crossing specifically calls for microspikes or crampons appropriate to current glacier conditions, trekking poles for stability on both the rocky approach and the icy pass itself, and glacier-grade sunglasses or goggles given the intense reflected sunlight off the snow and ice. A warm, wind-resistant outer layer is essential, since the pass itself is fully exposed and can be considerably colder and windier than the sheltered sections of trail lower down in either valley.
A headlamp is worth carrying even on a planned daytime crossing, since an early start in the dark or a longer-than-expected day on the glacier is not unusual, and dry gloves are important given how much contact with snow and ice the crossing involves compared with the rest of a standard Everest Base Camp or Gokyo itinerary. As with any high-altitude crossing in the region, carrying enough water and high-energy food for a six-to-eight hour day with no resupply options between Dzongla and Thagnak is essential.
Do I need special travel insurance for the Cho La glacier crossing
Yes. Standard trekking insurance sometimes excludes glacier travel or mountaineering-adjacent activities even when it covers trekking at the same altitude, so it is worth confirming specifically with your insurer that a policy covers glacier crossings, not just trekking above a certain elevation. Combined with confirmed helicopter evacuation coverage up to at least 6,000 meters, this is one of the more important details to check before committing to a Cho La itinerary.
Can Cho La be crossed in a single long day from Everest Base Camp
No, the standard itinerary always includes an overnight at Dzongla before the crossing rather than attempting it directly from Lobuche or Gorak Shep in one very long push, both because of the distance and elevation involved and because arriving at the start of the technical section already tired significantly increases risk. Operators who propose skipping the Dzongla overnight to save a day are cutting a meaningful safety margin, and this is a detail worth confirming when comparing itineraries.
Porters and Support Staff on the Cho La Route
A porter is strongly recommended for a Cho La itinerary given the length and cumulative demand of a combined Everest Base Camp, Cho La, and Gokyo trip, and most package itineraries include porter support as standard. On the crossing day itself, however, porters typically carry loads only as far as conditions safely allow on the glacier, and some operators use dedicated, specially experienced staff for the technical section rather than the trekker’s usual porter, which is worth asking about specifically when booking. Our guide to porters on the Everest Base Camp trek covers hiring, fair wages, and tipping norms that apply equally to a Cho La and Gokyo itinerary.
The guide-to-client ratio matters more on Cho La than on many other sections of the Everest region trails, since a single guide managing a large group across an icy, crevassed glacier has less capacity to give individual attention than on a straightforward trekking day. Smaller groups, or itineraries with an assistant guide for larger parties, generally handle the crossing more safely and with less time spent waiting in exposed, cold conditions while each trekker is fitted with traction equipment.
What altitude sickness medication is commonly used on Cho La itineraries
Diamox is the medication most commonly used preventively by trekkers on Cho La and other high-altitude Everest region itineraries, taken under guide or medical guidance rather than as a substitute for proper acclimatization. It does not eliminate altitude risk and should not be treated as a reason to skip acclimatization days or rush the itinerary; it is a supplementary tool, not a replacement for a well-paced schedule.
Cho La and Cholatse: A Dramatic Backdrop
The pass takes its name from its proximity to Cholatse, the striking, sharply pointed peak that dominates the skyline south of the crossing and is visible for much of the approach from Dzongla. While Cholatse itself is a serious technical climbing objective well beyond the scope of a standard trekking itinerary, its presence gives the Cho La crossing a visual drama that many trekkers rate among the most memorable single vistas of their entire trip, a jagged, glaciated summit rising directly above the trail rather than a distant horizon peak.
Photographers crossing Cho La in clear morning light often find the combination of Cholatse’s dramatic face, the glacier underfoot, and the surrounding high peaks produces some of the most striking images of an Everest region trek, provided weather cooperates and there is time to pause partway across for a proper look, always balanced against the guide’s assessment of how much time is safe to spend on the exposed glacier section itself.
Is Cho La open year-round
Technically the pass can be crossed in any season with the right equipment and an experienced guide, but the combination of near-constant snow cover, colder temperatures, and higher avalanche and crevasse risk in winter and monsoon makes spring and autumn the only seasons most operators recommend for anyone other than highly experienced, specially equipped parties. Outside those two windows, conditions can change from manageable to genuinely hazardous with a single significant snowfall, which is why season selection matters more for Cho La than for many other sections of Everest region trekking.
What should I do if I feel anxious about the glacier crossing
Tell your guide before the crossing day, not partway across; a guide who knows a client is nervous can adjust pacing, offer extra reassurance or a supporting arm on the trickier sections, and explain exactly what to expect before you are committed to the exposed part of the route. Most trekkers who feel apprehensive beforehand find the actual crossing more manageable than anticipated once moving, particularly with a calm, experienced guide setting the pace and choosing the safest line across the ice.
How does Cho La fit if I only have time for Everest Base Camp
If your schedule only allows for the standard Everest Base Camp trek without the extension to Gokyo, Cho La is not necessary and the classic out-and-back route through Lobuche and Gorak Shep remains the simpler, shorter option. Cho La only makes sense as part of an itinerary that specifically includes the Gokyo Lakes or the full Three Passes circuit, since its entire purpose is connecting those two valleys rather than serving as a destination in its own right.
Trekkers deciding between a standard Everest Base Camp trip and a longer combined itinerary including Cho La should weigh the extra week or so of time and the added technical demand against how much they specifically want to see the Gokyo Lakes and cross a genuine high-altitude glacier, a worthwhile trade-off for many but not a necessary addition for everyone visiting the region for the first time.
Cho La is the crossing that turns a standard Everest Base Camp trip into a genuine high-mountain traverse, and for trekkers with the fitness, time, and appetite for a real glacier crossing, it is one of the most rewarding single days available anywhere in the Khumbu.

Final tips for a safe Cho La crossing
Book with an operator who guides this crossing regularly, insist on a buffer day in the itinerary, confirm your insurance covers glacier travel, pack proper traction equipment, and trust your guide’s judgment if they decide to delay for weather. These simple decisions, made well before you ever reach Dzongla, do more to keep you safe on Cho La than anything you can control on the crossing day itself.
There is no better feeling in the Khumbu than standing on the ice at 5,420 meters with Cholatse towering above and the Ngozumpa Glacier stretching out below, knowing you crossed one of the Himalaya’s genuine high passes on your own two feet.
