The Cho La Pass Trek is one of Nepal’s most exciting and rewarding trekking routes. It combines the world-famous Everest Base Camp (EBC), the stunning Gokyo Lakes, and the challenging Cho La Pass (5,420 m / 17,782 ft) into one unforgettable journey. This trek is also widely searched as Chola Pass Trek, EBC Cho La Pass Trek, EBC Cho La Pass Gokyo Trek, and EBC–Kala Patthar–Cho La Pass Trek.
Cho La Pass Trek – most trekkers choose between Everest Base Camp and Gokyo Lakes — two extraordinary but distinctly different Khumbu experiences. The EBC route follows the Dudh Koshi valley to the foot of the world’s highest mountain — dramatic, culturally rich, and historically iconic. The Gokyo route follows the Ngozumpa Glacier valley to a chain of sacred turquoise lakes with arguably even more spectacular mountain panoramas than EBC itself.
The Cho La Pass connects both routes, and choosing to cross it rather than retrace your steps means you get everything. You earn both destinations, cross a serious high-altitude pass in between, and experience the Khumbu in its full geographical breadth rather than a single valley. For many experienced trekkers who have done EBC alone and returned to Nepal for the Cho La route, the Gokyo valley and the pass crossing are considered even more memorable than the base camp itself.
The Cho La Pass at 5,420m is one of the more technically demanding sections of any standard Khumbu trekking itinerary. The approach from Dzonglha climbs through a boulder field before reaching the glaciated upper section — a steep slope of permanent snow and ice where crampons are typically required. The final metres to the col are the steepest, and your guide will use fixed ropes to assist the crossing if conditions demand.
The crossing itself takes 4–5 hours from Dzonglha to Thagnak on the Gokyo side. The descent from the pass is steep on rock and scree — trekking poles and careful footwork are essential. The reward for crossing is immediate — the view into the Gokyo valley from the col is one of the finest panoramic reveals in all of Himalayan trekking.
The pass is generally best crossed from east to west (as in this itinerary — Dzonglha to Thagnak) in the morning before afternoon clouds build. Departing Dzonglha at 5–6 AM allows you to cross in the early morning window when snow is frozen, and conditions are most stable.
Kala Patthar (5,545m) is a black rocky promontory on the south ridge of Pumori, rising above Gorakshep at the head of the Khumbu Glacier. It is the closest point accessible to trekkers to the summit of Mount Everest and the finest viewpoint for the mountain available without technical climbing equipment.
The pre-dawn ascent from Gorakshep takes 2–3 hours in the dark with headlamps. Arriving at the summit as the first light touches Everest’s summit pyramid — turning the ice and snow from deep purple to gold — is one of the most profound experiences in adventure travel. The panorama from Kala Patthar includes Everest (8,848m), Lhotse (8,516m), Nuptse (7,861m), Pumori (7,161m), Changtse, and the full sweep of the Khumbu Glacier below.
The Gokyo Lakes are a chain of six glacial lakes in the upper Dudh Koshi valley — the largest chain of glacial lakes in the Himalayas and protected as a Ramsar Wetland of International Importance. The third lake at Gokyo village (4,750m) is the most famous — a deep turquoise colour set against the white expanse of the Ngozumpa Glacier and the peaks of Cho Oyu, Everest, and Lhotse above.
Gokyo Ri (5,357m) — the steep hill above the village — offers one of the five or six finest mountain panoramas in all of Nepal. The view from the summit encompasses Everest, Lhotse, Makalu, Cho Oyu, and dozens of lesser peaks across a 360-degree sweep — with the full length of the Ngozumpa Glacier stretching away below you in the opposite direction.
The itinerary includes two dedicated acclimatization days — in Namche Bazaar (3,440m) on Day 5 and in Dingboche (4,350m) on Day 8. Both are essential and non-negotiable. The Namche rest day typically involves a hike to the Everest View Hotel at Syangboche (3,780m) for classic acclimatization practice. The Dingboche rest day involves a hike toward Chhukung or Nangkar Tshang hill for 4,000m+ exposure before returning to sleep lower.
Following the established acclimatization schedule significantly reduces altitude sickness risk on the high sections — Lobuche (4,940m), Gorakshep (5,164m), Kala Patthar (5,545m), and the Cho La crossing (5,420m).
The Cho La Pass Trek is rated challenging — primarily due to the sustained altitude, the length of the itinerary, and the technical demands of the Cho La crossing. Daily walking of 3–7 hours on well-established trails is manageable for trekkers with good base fitness. The Cho La Pass crossing requires crampon use and comfort on steep snow — your guide provides full instruction and leads all technical sections. Prior experience on trails above 4,000m is recommended but not mandatory.
The two best seasons are spring (March to May) and autumn (September to November). Autumn is generally preferred for this route — October offers the clearest skies, most stable weather, and best snow conditions on the Cho La crossing. Spring brings blooming rhododendrons on the lower trails and excellent mountain visibility. Both the monsoon season (June to August) and winter (December to February) are not recommended — monsoon brings cloud and rain, winter brings extreme cold and deep snow on the Cho La.

If you want more than just Everest Base Camp, this trek is the perfect choice. We experienced Sherpa culture, crossed a high mountain pass, explored the stunning Gokyo Lakes, and enjoyed breathtaking views throughout the journey. The guide was friendly, professional, and always encouraged us during the tougher sections. It felt like a true Himalayan adventure from beginning to end.
I spent months comparing different trekking companies before choosing Alliance Treks, and I’m glad I did. The itinerary was well paced with proper acclimatization days, which made a huge difference at higher altitudes. The Cho La Pass crossing was unforgettable, and Gokyo Ri offered the best mountain views I’ve ever seen. Everything from airport pickup to the final flight back to Kathmandu was organized perfectly.
The Cho La Pass Trek was everything I hoped for and more. Crossing the pass was definitely the most challenging part, but the views made every step worth it. Visiting Everest Base Camp, watching sunrise from Kala Patthar, and ending the trek at the beautiful Gokyo Lakes gave me the complete Everest experience. Our guide was knowledgeable and always made sure everyone was safe and well acclimatized. I would happily trek with Alliance Treks again.
From the moment I arrived in Kathmandu until the end of the trek, everything was handled professionally. The tea houses were comfortable, the guide shared interesting stories about the mountains and local culture, and the scenery became more impressive every day. Crossing Cho La Pass and reaching Gokyo Lakes were the highlights of my trip. I returned home with unforgettable memories and would recommend Alliance Treks to anyone planning an Everest region trek.
This trek pushed me physically, especially on the day we crossed Cho La Pass, but it became one of the greatest achievements of my life. Standing on Kala Patthar at sunrise and seeing Everest glowing in the morning light is a memory I’ll never forget. The team from Alliance Treks was supportive, experienced, and always focused on our safety. I highly recommend this trek for anyone looking for a real mountain adventure.
