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.

Highlights of the Everest Three High Passes Trek

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.

Best Time to Trek

The best seasons for the Everest Three High Passes Trek are:

  • 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.

Trekking Difficulty and Preparation

The Everest Three High Passes Trek is rated as strenuous due to high elevations, long trekking days, and remote conditions. It is suitable for physically fit and experienced trekkers who have previously hiked at altitude.

  • Acclimatization: Essential for avoiding altitude sickness. Most itineraries include rest days in Namche Bazaar and Dingboche.

  • Training: Cardiovascular fitness, endurance, and strength training before the trek are highly recommended.
  • Trekking Gear: Required equipment includes down jackets, layered clothing, warm gloves, sleeping bags, trekking poles, and potentially crampons or microspikes (especially for icy sections of Cho La Pass).
