05 June 2025
Planning a Trip to Nepal?
The Everest Three High Passes Trek is one of the most adventurous, comprehensive, and scenic treks in the Everest region of Nepal. This high-altitude circuit trek goes beyond the traditional Everest Base Camp Trek route, incorporating the crossing of three major Himalayan passes: Kongma La (5,535m), Cho La (5,420m), and Renjo La (5,340m). It offers trekkers a thrilling and immersive experience in the heart of the Khumbu, linking major viewpoints, cultural villages, and secluded alpine valleys. This trek not only challenges physical endurance but also rewards adventurers with some of the most spectacular vistas in the Himalayas, including panoramic views of Mount Everest, Lhotse, Nuptse, Makalu, Cho Oyu, and Ama Dablam.
The route offers unmatched diversity, from panoramic viewpoints like Kala Patthar and Gokyo
Ri to immersive Sherpa culture in remote villages such as Thame and Chhukung. With dramatic mountain vistas, spiritual encounters, glacial lakes, and quiet alpine trails, the trek stands out as one of Nepal’s most complete and rewarding adventures for seasoned trekkers.
Three Challenging High Passes: Cross Kongma La, Cho La, and Renjo La,each offering a unique high-altitude challenge and breathtaking views of towering Himalayan peaks.
Everest Base Camp & Kala Patthar: Visit the iconic Everest Base Camp and hike to Kala Patthar (5,545m) for the best close-up view of Mount Everest.
Gokyo Valley and Lakes: Explore the pristine, glacial Gokyo Lakes and ascend Gokyo Ri (5,360m) for sweeping panoramas over Everest and Cho Oyu.
Remote Valleys and Villages: Discover traditional Sherpa settlements like Chhukung, Dzongla, Thagnak, Gokyo, and Thame, experiencing authentic Himalayan culture.
Cultural and Spiritual Richness: Encounter ancient monasteries, prayer flags, and mani walls along the route, reflecting the deep Buddhist heritage of the Khumbu region.
Less Crowded Trails: While Everest Base Camp can be busy, sections of the Three Passes route, especially Kongma La and Renjo La, offer a quieter and more remote trekking experience.
Detailed Look at the Three Passes
1. Kongma La (5,535 m)
The highest and most remote of the three passes, Kongma La connects Chhukung with Lobuche, bypassing the main Everest Base Camp highway.
Trail highlights: Crossing the Khumbu Glacier, panoramic views of Nuptse, Lhotse, Makalu, and Ama Dablam, and a true sense of wilderness.
Challenge: Steep climb, loose scree, no teahouses between Chhukung and Lobuche — carry enough water and snacks.
2. Cho La (5,420 m)
Probably the most famous pass, Cho La connects Dzongla to the Gokyo Valley.
Trail highlights: Stunning glacier traverse at the top, sharp rock walls, turquoise lakes below, and a thrilling, icy crossing.
Challenge: Snow and ice can make this pass tricky — microspikes or crampons may be needed, especially in spring and late autumn.
3. Renjo La (5,340 m)
Renjo La connects Gokyo with the quiet Thame Valley and is often considered the most scenic pass, offering jaw-dropping views of Everest,Cho Oyu,and Gokyo Lakes.
Trail highlights: Massive Himalayan panorama, far fewer trekkers, and a rewarding descent into authentic Sherpa villages.
Challenge: Long ascent from Gokyo, cold winds at the top, and steep descent.
Spring (March to May): Stable weather, rhododendron blooms, and excellent visibility make this a popular and beautiful time for trekking.
Autumn (late September to November): Clear skies, crisp air, and mild temperatures offer ideal conditions for high-altitude trekking and photography.
Avoid the summer monsoon (June to August) due to heavy rainfall, muddy trails, and low visibility. Winter (December to February) can be extremely cold, and heavy snow may block the passes.

This trek is considered strenuous due to the high altitude, long trekking days, and the need to cross three passes above 5,000 meters. Prior high-altitude trekking experience and good physical fitness are essential.
While it's possible to trek independently, hiring a licensed guide is highly recommended for safety, navigation across the passes, and cultural insight.
You will need the Sagarmatha National Park Entry Permit and the Khumbu Pasang Lhamu Rural Municipality Permit, both of which can be arranged in Kathmandu or at entry checkpoints.
Altitude sickness is a major concern. Prevent it by ascending slowly, taking acclimatization days, staying hydrated, and avoiding alcohol. Medications like Diamox can help, but consult your doctor beforehand.
ATMs are available in Namche Bazaar, but unreliable. It' best to carry enough cash. Mobile overage (mainly Ncell or NTC) is available in many areas, though patchy in remote parts.
Temperatures can drop below -15°C (5°F) at night or during early mornings on the passes, especially in spring and autumn. Proper clothing is essential.
Essentials include a down jacket, sleeping bag (-10°C or lower), base layers, waterproof shell, gloves, sunglasses, trekking poles, headlamp, water bottles, and snacks. Bring crampons if trekking in early spring or late autumn.
