The Everest region in Nepal is home to some of the most breathtaking trekking routes in the world, but few match the thrill and challenge of the Everest Three Pass Trek. This demanding journey leads adventurers across three high-altitude mountain passes over 5,000 meters, each offering stunning views and unforgettable experiences. Many first-time trekkers ask, “What is the three pass in Everest?” The answer lies in the names of the passes: Kongma La (5,535m), Cho La (5,420m), and Renjo La (5,360m). Together, these passes create a circuit that connects the major valleys of the Everest region and forms one of the most rewarding and complete trekking experiences in the Himalayas.
A Complete Circuit of the Everest Region
Unlike the traditional Everest Base Camp trek, which follows a single route to and from the base camp, the Three Pass Trek forms a loop through the Khumbu region. It not only includes a visit to Everest Base Camp but also takes trekkers through remote trails, high passes, glacier crossings, and quiet valleys less traveled by tourists.
This trek is ideal for those looking for a more challenging alternative to the classic routes, and it’s a favorite among experienced trekkers who want to explore deeper into the Everest region.
The Three Passes Explained
Kongma La Pass (5,535m):
The highest and most difficult of the three passes, Kongma La links the Chhukung and Lobuche valleys. It offers dramatic views of Lhotse, Nuptse, and Makalu. The trail here is steep, rocky, and often covered with snow, requiring physical stamina and careful pacing.
Cho La Pass (5,420m):
This pass connects Dzongla to the beautiful Gokyo Valley. While slightly lower than Kongma La, Cho La involves a glacier crossing and can be treacherous if weather conditions are poor. The reward, however, is worth it—stunning views and the approach to the turquoise Gokyo Lakes.
Renjo La Pass (5,360m):
The final pass, Renjo La, is considered the most scenic. It offers a less crowded trail and provides majestic views of Everest, Gokyo Lake, and the surrounding peaks. This pass connects the Gokyo Valley with the village of Thame, eventually looping back to Namche Bazaar.
Physical Demands and Acclimatization
The Everest Three Pass Trek is physically and mentally demanding. It requires good fitness, high-altitude trekking experience, and proper acclimatization. Trekkers usually spend 18 to 21 days completing the route, allowing time to adjust to the altitude and enjoy key highlights such as Everest Base Camp, Kala Patthar, and Gokyo Ri.
Acclimatization days are essential, especially before tackling each pass. Without them, the risk of altitude sickness increases significantly. Guided treks often include well-planned rest days in places like Namche Bazaar and Dingboche.
Best Time to Trek
The ideal seasons for the Three Pass Trek are spring (March to May) and autumn (September to November). These periods offer clear skies, moderate temperatures, and the best chances for safe and successful pass crossings. Winter brings extreme cold and snow-covered trails, while the monsoon season makes paths slippery and clouds obscure the views.
A Journey Worth the Effort
Though challenging, the Everest Three Pass Trek is one of the most fulfilling adventures in the Himalayas. Trekkers experience the full range of the Khumbu region's beauty—from soaring peaks and serene lakes to Sherpa villages and Buddhist monasteries. For those who seek a true test of endurance and a deeper exploration of Everest, this trek is second to none.
