Everest Base Camp is a famous trek. The Three High Passes is the one serious trekkers whisper about. It crosses three passes above 5,300 m, links Everest Base Camp with the Gokyo Lakes, and takes about 20 days. It’s often called the ultimate Everest trek.
It’s also known for being tough. So the real question isn’t “Is it amazing?” It’s “Is it too hard for me?” This guide gives you an honest answer. It covers what each pass is like, what makes the trek so demanding, and who should (and shouldn’t) take it on.
Quick Answer
The Three High Passes is strenuous, but not technical. You don’t need climbing skills, ropes, or an ice axe. What you do need is strong fitness, good mental grit, and ideally some earlier high-altitude trekking. If Everest Base Camp felt manageable and you want more, you may be ready. If it would be your first big trek, start lower.
The Three Passes at a Glance
| Pass | Height | What it connects | Typical walking time | Why it’s tough |
|---|---|---|---|---|
| Kongma La | 5,535 m | Chukhung or Dingboche side to Lobuche | 7–8 hrs | The highest of the three, with a steep rocky climb and moraine |
| Cho La | 5,420 m | Dzongla to Thangnak or Gokyo | 6–9 hrs | A glacier near the top, with ice and loose rock |
| Renjo La | 5,360 m | Gokyo to Lungden or Marlung | 7–8 hrs | A long climb, but with the best views of Everest and the Gokyo Lakes |
Heights vary slightly by source (for example, Renjo La is also quoted at 5,340 m). Many trekkers say Kongma La is the hardest day, Cho La is tricky because of the ice, and Renjo La is the easiest.
What the Route Looks Like
The loop usually flies into Lukla, climbs to Namche Bazaar, and follows the classic Everest route through Tengboche and Dingboche. From there, it crosses the three passes and visits Everest Base Camp (5,364 m), Kala Patthar (5,545 m), and Gokyo Ri (about 5,357 m), then returns to Lukla.
It can be done clockwise (Renjo La first) or anticlockwise (Kongma La first). Both work, and the order changes how you build up to altitude, so check the plan on the itinerary you choose.
Snowbank’s Everest Three High Passes Trek takes 20 days and starts from $1,699 per person.
Why It’s So Demanding
1. Long stretches at very high altitude.
You spend many days above 4,500 m and cross three passes above 5,300 m. Lobuche sits at about 4,910 m, and Gorak Shep at about 5,164 m. Your body gets little chance to recover fully.
2. Very long pass days.
Each crossing takes about 6 to 9 hours, often starting before dawn.
3. Rough terrain.
Expect steep rocky climbs, loose moraine, and boulder fields. Cho La has a glacier near the top, with ice and, at times, snow.
4. Changing weather.
Cold, wind, and snow can arrive fast. If Cho La is closed, trekkers often have to take a longer alternative route through Dole and Phortse instead.
5. Basic lodges and cold nights.
Rooms at this height are simple and unheated. Sleep is often poor, and you may be tired for days.
6. Cumulative fatigue.
No single day is the problem. It’s the 20 days in a row that wears you down, so the final pass can feel harder than the first.
Do You Need Technical Skills?
No. The Three High Passes is a trekking route, not a mountaineering one. You won’t need ropes, harnesses, or an ice axe. But in icy or snowy conditions, microspikes or crampons may be useful on Cho La or Kongma La. Ask your operator what gear they provide and recommend.
How Does It Compare with Everest Base Camp?

Are You Ready? A Simple Checklist
You’re probably ready if you:
- Have completed a high-altitude trek before, such as Everest Base Camp, the Annapurna Circuit, or another route above 4,500 m
- Can walk 6 to 8 hours a day on steep ground
- Have trained for several months with cardio, leg strength, and long hikes
- Feel comfortable with basic lodges, cold nights, and limited showers
- Can handle a long trip away from home
You should probably wait if you:
- Have never trekked at altitude
- Have heart, lung, or knee problems without a doctor’s approval
- Want a relaxed holiday rather than a challenge
- Only have two weeks
Altitude Safety
At these heights, altitude illness is a serious risk for any trekker. Climb slowly, take rest days, report symptoms early, and never go higher with symptoms. Experts also suggest raising your sleeping altitude gradually above about 3,000 m. Read our altitude sickness guide and talk to your doctor before booking.
Before you sign up, ask your operator how many acclimatization days the itinerary has, and where they fall.
Best Time to Go
Spring (March–May) and autumn (September–November) are the best seasons, with clearer skies and more stable weather. Snow and ice make the passes much harder in winter, and the monsoon brings poor visibility and slippery trails.
Permits
The trek goes through Sagarmatha National Park, so you need the park permit and the local Khumbu permit, together about NPR 6,000 (roughly $44). A licensed guide is also required. See our Nepal trekking permits guide.
What to Pack (The Extras)
On top of the normal Everest packing list, think about:
- A warm sleeping bag, rated for very cold nights
- Trekking poles for steep descents
- Sunglasses or goggles and strong sun protection
- Microspikes or crampons, if your operator recommends them
- Layers for big temperature swings
- A headlamp for pre-dawn starts
Easier Ways to Do Part of It
Not ready for all three passes? You still have options:
- Everest Base Camp (about 15 days) for the classic route. See Everest Base Camp Trek – 15 Days.
- Gokyo Lakes or Cho La itineraries, which cross fewer passes.
- Everest Base Camp with Helicopter Return, if time is the issue. See how the helicopter return works .
