The Everest Three Passes trek is for experienced hikers who want more than the classic Base Camp route. It links the Gokyo Lakes, Everest Base Camp and Chukhung valleys by crossing three high passes: Renjo La (around 5,350 m), Cho La (5,420 m) and Kongma La (5,535 m). It is one of Nepal's most rewarding and demanding circuits, and it rewards preparation with some of the finest mountain scenery on Earth. This guide explains the route, a realistic itinerary, difficulty, cost, permits and how to prepare.
Route overview
Most itineraries run counter-clockwise or clockwise over 18–21 days and cover roughly 150 km of trails. You pass Namche Bazaar, Thame, Gokyo, Dzongla, Lobuche, Gorak Shep, Dingboche and Chukhung. Along the way you can add side trips to Kala Patthar, Gokyo Ri and Chukhung Ri. Reported pass altitudes vary slightly between sources: Renjo La appears as 5,340–5,360 m, Cho La as about 5,420 m and Kongma La as about 5,535 m, so treat the numbers as approximate.

Many operators run the route in the opposite direction, starting with Kongma La. Each direction has trade-offs for acclimatisation and the difficulty of the Cho La crossing, so ask your agency to explain their reasoning.
The three passes in detail
Renjo La. Often described as the easiest of the three, it offers one of the best views of Everest, with Gokyo Lake below. The climb is steady, and the descent to Gokyo is on a rocky trail.
Cho La. This is the most technical crossing, involving a steep rocky ascent and, in many years, a glacier on the far side. In icy conditions microspikes and caution are essential. Starting early gives you the best chance of firm snow.
Kongma La. The highest pass, with a steep climb and a long day. The view over Chukhung and Island Peak is superb, but the altitude and length make it demanding.
Difficulty
This trek is strenuous. Days are long, glacier crossings can be icy, and the passes can be affected by snow. You need excellent fitness, solid previous high-altitude experience and a flexible schedule. Review our altitude sickness guide and consider shorter options like the Gokyo Lakes trek or the classic Everest Base Camp trek if this would be your first Himalayan expedition.
Fitness and preparation
Start training at least 12 weeks before departure. Combine long hikes with a loaded pack, stair climbing, leg strength work and back-to-back days. Our training plan is a good base, and for the Three Passes you should lengthen your weekend hikes and add steep downhill work. Break in your boots thoroughly and test microspikes and poles before you travel.
Cost
Budget USD 2,000–3,500 for a guided trip depending on group size, season and services. The Lukla flights remain a large part of the cost; see the Lukla flight guide and Everest cost guide for typical figures. Extra days for weather, insurance and tips add to the total.
Permits
You need the Sagarmatha National Park permit and the Khumbu municipality entry fee, both arranged by your agency. See the permit guide for current details and rules.
Best time
Mid-October to early November and late April to May. Cho La and Kongma La are most dangerous in fresh snow, so a flexible schedule helps. See the best time guide for detailed seasonal conditions.
Gear checklist for the passes
- Four-season sleeping bag (about −15 to −20 °C comfort in cold months)
- Insulated jacket, thermal layers, waterproof shell and warm gloves
- Microspikes and trekking poles
- Sunglasses with category 3–4 lenses and strong sunscreen
- Headlamp with spare batteries
- Water purification and a thermos
- A personal medical kit and any prescribed altitude medication
Our packing list covers every item, with notes on what to rent in Kathmandu.
Acclimatisation strategy for a long high-altitude loop
The Three Passes route spends many days above 4,000 m, so acclimatisation is the key to finishing. Most itineraries include two rest days, in Namche and in Gokyo or Dingboche, and a sensible plan keeps the daily gain in sleeping altitude modest. Because the loop repeatedly climbs to passes above 5,300 m and descends to sleep lower, it supports "climb high, sleep low" naturally. Still, the cumulative fatigue is real. Listen to your guide, eat well and add a spare day if you feel unwell. Skipping rest to save time is the most common reason trekkers abandon the circuit.
Snow, ice and weather on each pass
Conditions change by season and by the week. After snowfall, the approach to Cho La can be slippery, and the glacier section may need extra care. Renjo La is generally the most forgiving but can be windy. Kongma La is long and exposed, with a steep final climb. Guides check conditions with other groups and lodge owners the evening before and decide whether to go. Carry microspikes, gaiters and gloves in cold months, and never cross in poor visibility.
Food, lodges and facilities
Lodges on the circuit range from comfortable to very basic, and some high-altitude stops such as Thangnak and Lungden are small. Meals follow the usual Khumbu menu, with limited choice at the highest stops. Carry snacks (nuts, chocolate, energy bars) for pass days, and a thermos for hot drinks. Hot showers are rare at the highest lodges and Wi‑Fi is unreliable, so plan to be offline for much of the trek.
Day difficulty at a glance
| Section | Rating | Why |
|---|---|---|
| Lukla to Namche | Moderate | Steep climb to Namche |
| Thame to Lungden | Moderate | Gradual ascent into a remote valley |
| Renjo La crossing | Hard | Long climb and steep descent |
| Thangnak to Dzongla via Cho La | Very hard | Glacier crossing and rock |
| Lobuche to Gorak Shep and Base Camp | Hard | Altitude and distance |
| Chukhung to Dingboche via Kongma La | Very hard | Highest pass and a long day |
Choosing an operator for a high-pass trek
Ask the operator about guide experience on the passes, emergency equipment (oxygen, a satellite phone, a first-aid kit with an oximeter), the ratio of guides to clients and what happens if a pass is closed. A good agency explains its contingency plans, pays and equips its staff fairly, and carries out a daily health check. Our responsible travel guide lists questions to ask any operator.
Safety essentials
- Hire an experienced guide and consider an extra guide for larger groups.
- Carry travel insurance that covers high-altitude trekking and helicopter evacuation above 5,500 m.
- Do not cross passes in bad weather, and keep spare days.
- Descend if altitude symptoms worsen; see our altitude guide.
- Follow the guidance of the Himalayan Rescue Association, whose aid posts offer free altitude advice in the Khumbu.
Is it worth it?
For fit, experienced trekkers, yes. The Three Passes combines Nepal's best Everest region scenery with real adventure and fewer crowds on several sections. If you are still deciding, compare the classic trek in our 14-day itinerary and the quieter alternatives in less crowded treks in Nepal.
Who should do the Three Passes, and who should wait?
The circuit suits trekkers who have already completed a high-altitude trek, who are comfortable walking six to eight hours a day and who can tolerate cold, basic lodges for nearly three weeks. If this would be your first Himalayan trek, start with the classic route or a shorter alternative, and come back to the passes later. A trip that ends early because of altitude or fatigue is far less satisfying than a well-chosen first trek followed by a bigger objective.
