Mountain Passes to Cross During 3 Passes Trek – A Complete Guide for Trekkers
The Mountain Passes to Cross During 3 Passes Trek are among the most breathtaking and challenging in the Himalayas, attracting adventure enthusiasts from all over the world. This legendary trek combines high-altitude adventure with spectacular scenery, taking you over Kongma La Pass, Cho La Pass, and Renjo La Pass — three of Nepal’s most iconic crossings.
From snow-clad ridges to glacial landscapes, the trek is a true test of endurance and determination. Each pass offers a unique perspective, whether it’s standing above the Khumbu Glacier, gazing over the Gokyo Lakes, or witnessing the sunrise over Mount Everest. For safety and to meet local regulations, you must be accompanied by a certified trekking guide throughout this journey.
Overview of the 3 Passes Trek
The Three Passes Trek weaves through the heart of the Khumbu region, offering a circuit route that links Everest Base Camp, Gokyo Valley, and Thame Valley.
Trekkers can take the clockwise route starting from Namche Bazaar and moving towards Kongma La, or the counter-clockwise option beginning with Renjo La Pass.
Along the way, you’ll pass through charming Sherpa villages, visit ancient monasteries like Tengboche Monastery, and walk amidst towering peaks including Lhotse, Ama Dablam, Cho Oyu, and Makalu. The trek spans around 18–21 days, depending on acclimatization days and side trips.
Since the trek traverses Sagarmatha National Park, trekkers must obtain the Sagarmatha National Park Permit and Khumbu Pasang Lhamu Rural Municipality Permit.
The 3 Passes Trek is considered strenuous due to its altitude profile, reaching over 5,000 meters on three separate occasions. But for those prepared, it’s the ultimate Himalayan adventure.
Kongma La Pass (5,535 m) – The Highest of the Three
Where It Is
Kongma La Pass lies between Chhukhung and Lobuche, making it the highest and most demanding of the three passes. It’s usually crossed after a night in Chhukhung, giving trekkers a head start for the steep ascent.
Why It’s Special
At the top, trekkers are rewarded with awe-inspiring views of Makalu, Lhotse, and the vast expanse of the Khumbu Glacier. The trail here feels truly remote, with barely any signs of human habitation.
Challenges
- Steep ascents and descents with rocky and often snow-covered paths
- No teahouses or water sources along the crossing day
- Thin air and exposure to the elements make acclimatization essential
Tips
- Start early to avoid afternoon weather changes
- Carry enough water and snacks, as there are no facilities en route
- Have your camera ready for panoramic shots of Himalayan giants
Cho La Pass (5,420 m) – Gateway to Gokyo Valley
Where It Is
Cho La Pass connects Dzongla with Thagnak and acts as the bridge between the Everest Base Camp route and the Gokyo Valley.
Why It’s Popular
The crossing offers dazzling views of Ngozumpa Glacier, the longest glacier in the Himalayas, as well as glimpses of the turquoise Gokyo Lakes.
Challenges
- The ascent can be icy and slippery, especially in colder months
- Rockfalls and loose gravel in some sections
- Glacier crossing requires steady footing and caution
Tips
- Trekking poles are very helpful for stability
- Crampons or microspikes can make the icy sections safer
- Stay hydrated to combat altitude effects
Renjo La Pass (5,360 m) – The Scenic Final Pass

Where It Is
Situated between Gokyo and Lungden, Renjo La Pass is often the final crossing on the 3 Passes circuit.
Why It’s a Favorite
From the top, you can enjoy perhaps the best panoramic view in the Everest region, with Everest, Makalu, Cho Oyu, and the shimmering Gokyo Lakes all in one frame. The sunrise here paints the peaks in golden light, a sight that stays with trekkers forever.
Challenges
- Less steep than Kongma La but still demands stamina
- Cold winds near the summit ridge
- Descent towards Thame Valley can be long and tiring
Tips
- Start before dawn to catch the sunrise over Gokyo
- Dress in layers to adjust for changing temperatures
- Take breaks to savor the views rather than rushing through
Best Time to Do the 3 Passes Trek
The most suitable seasons for the Three Passes Trek are:
- Spring (March–May) – Clear skies, blooming rhododendrons, stable weather
- Autumn (September–November) – Crisp air, best mountain visibility, pleasant daytime temperatures
Monsoon months (June–August) bring heavy rain, leeches, and poor visibility, while winter (December–February) can cause heavy snow accumulation, making passes impassable.
Preparation & Safety Tips
- Train for endurance: Cardiovascular fitness, leg strength, and trekking experience help enormously
- Pack for varied conditions: Layered clothing, down jacket, gloves, and waterproof gear
- Acclimatization is key: Include rest days at Namche Bazaar and Dingboche
- Stay with a certified trekking guide for route safety, emergency assistance, and navigation
- Hydration & nutrition: Carry snacks, drink plenty of water, and avoid overexertion
- AMS awareness: Know the symptoms and act early
