Our team outlines the complete Everest Three Passes trek itinerary, breaking down daily walking hours, altitudes, and rigorous acclimatization steps.
Mastering the high altitude circuit
Our team guides hundreds of trekkers through the Khumbu each season, and the Everest Three Passes route remains our most demanding circuit. Spanning Renjo La (5,360 m), Cho La (5,420 m), and Kongma La (5,535 m), this traverse demands serious stamina, solid route experience, and careful management of daily elevation profiles. When planning this loop, understanding how each pass affects your body is essential, particularly given the risks outlined in our guide on altitude sickness on the everest base camp trek: symptoms, prevention, and descent. We begin our journey with the mandatory flight from Kathmandu to Lukla (2,840 m), securing our Sagarmatha National Park entry permits at the Monjo checkpoint before pushing deeper into Sherpa territory.
Day-by-day itinerary and elevation profile
Our standard 19-day itinerary builds in crucial rest days at Namche Bazaar and Dingboche to mitigate acute mountain sickness. Below is the precise breakdown of daily walking distances, camp elevations, and net gains our lead guides track on every departure.
- Fly Kathmandu (1,400 m) to Lukla (2,840 m), trek to Phakding (2,610 m) — 4 hours.
- Trek Phakding to Namche Bazaar (3,440 m) — 6 hours, crossing the Hillary Suspension Bridge over the Dudh Koshi.
- Acclimatization day in Namche Bazaar (3,440 m) — day hike to Everest View Hotel (3,880 m).
- Trek Namche Bazaar to Tengboche (3,860 m) — 5 hours, visiting the Tengboche Monastery.
- Trek Tengboche to Dingboche (4,410 m) — 5 hours, entering alpine scrub zones.
- Acclimatization day in Dingboche (4,410 m) — climb Nagarjun Hill (5,100 m).
- Trek Dingboche to Lobuche (4,940 m) — 5 hours, passing the Thukla memorial ridge.
- Trek Lobuche to Gorakshep (5,164 m), visit Everest Base Camp (5,364 m), return to Gorakshep — 7 hours.
- Climb Kala Patthar (5,643 m) in the morning, trek over Cho La pass to Dzongla (4,830 m) — 8 hours.
- Trek Dzongla to Gokyo (4,750 m) via Cho La (5,420 m) — 7 hours, walking alongside the Ngozumpa Glacier.
- Acclimatization day in Gokyo — climb Gokyo Ri (5,357 m).
- Trek Gokyo to Lungden (4,380 m) over Renjo La (5,360 m) — 7 hours.
- Trek Lungden to Namche Bazaar (3,440 m) — 6 hours.
- Trek Namche Bazaar to Lukla (2,840 m) — 7 hours.
- Fly Lukla to Kathmandu (1,400 m).
Pass comparison and technical demands
Navigating the three crossings
Each of the three passes presents distinct physical challenges. Kongma La requires crossing the boulder-strewn labyrinth of the Khumbu Glacier, while Cho La involves a steep, icy scramble just below the crest that frequently requires microspikes. Renjo La offers stone staircases built by local Sherpa herders, yet tests your endurance after weeks at altitude. For a broader look at how this compares to alternative routes, consult our notes on comparing difficulty between everest base camp and annapurna circuit. When preparing your gear load, remember that porter weight limits are strictly enforced at the Lukla weigh-station.
Key metrics across the loop
| Pass Name | Elevation (m) | Primary Approach Teahouse | Technical Challenge |
|---|---|---|---|
| Kongma La | 5,535 m | Lobuche or Chhukung | Khumbu glacier moraine traverse |
| Cho La | 5,420 m | Dzongla or Dragnag | Icy boulder scramble |
| Renjo La | 5,360 m | Gokyo or Lungden | Steep stone steps |
Essential preparation and safety
Our team enforces strict daily health checks, monitoring pulse oximetry readings every evening at dinner. You must pack appropriately for temperatures dropping to -15 °C at night in Gorakshep and Dzongla. To ensure you stay healthy throughout the multi-week effort, review our guidance on how to avoid altitude sickness during the everest trek. Below are the critical gear and preparation steps we mandate for every team member joining our autumn and spring departures:
- Certified insulated down jacket rated to at least -20 °C.
- Sturdy trekking boots broken in over a minimum of six months of prior day-hikes.
- Water purification tablets or an effective UV sterilizer for untreated teahouse tap water.
- A 30-litre daypack to carry your personal layers, water bladder, and emergency med kit.
- Valid insurance policy explicitly covering high-altitude trekking and helicopter evacuation up to 6,000 m.
- Physical training log showing at least three months of consistent cardiovascular conditioning.
