How Hard Are Nepal Treks? Difficulty Grades Explained

Most Nepal treks are long walks, not climbs. You do not need mountaineering skills for any of the 34 treks we list except one, but you do need to walk for most of the day, several days in a row, often on stone steps and at altitude. What makes one trek harder than another is mainly how high it goes, whether it crosses a high pass, how many days it lasts and how remote it is.

This guide explains what our four grades (easy, moderate, hard and extreme) actually mean. We worked them out from the data on our 34 trek pages: each trek's highest point, length, daily walking hours, overnight altitudes and passes. The altitude facts come from the US CDC's Yellow Book, the NHS and the UK's TravelHealthPro service.

What makes a Nepal trek hard

Altitude

Altitude matters more than anything else. Every breath carries less oxygen the higher you go, so the same walk feels harder at 4,500 m than at 1,500 m. Altitude illness becomes a real risk above about 2,500 m, according to the NHS and TravelHealthPro. The CDC puts the threshold at a sleeping altitude of about 2,450 m, sometimes lower.

The key number is the height you sleep at, not the height you reach in the day. Once you are above 3,000 m, the CDC, NHS and TravelHealthPro all advise against raising your sleeping altitude by more than 500 m a night. You also need rest days: the CDC suggests an extra night for every 1,000 m gained, and the NHS one every three to four days. That is why high treks take longer: the extra days are there to keep you safe, not to fill time. For symptoms and what to do about them, read our guide to altitude sickness on Nepal treks.

Fitness does not protect you. The CDC states that training and physical fitness do not affect your risk of altitude illness, and TravelHealthPro says the same. A fit trekker who climbs too fast is more at risk than a slower one who follows the plan.

High passes

A pass day is usually the longest day of a trek. On our itineraries, the crossings of the Thorong La, the Larkya La and the passes in the Everest region take seven to ten hours. You start before dawn, climb to the highest point of the trip, then face a long, steep descent on tired legs. In winter and early spring, snow can make a pass slower or close it.

Daily hours and total days

Most trekking days in Nepal are four to seven hours of walking. That sounds manageable until you do it for two or three weeks. A 5-day trek and a 24-day trek can have similar daily distances, but the long one wears you down and gives you more time to pick up a cold or a stomach bug.

Remoteness and camping

On the main routes in the Everest, Annapurna and Langtang regions you sleep in teahouses (family-run lodges) every night. On remote routes such as Upper Dolpo or Makalu to Kanchenjunga, there are stretches with no lodges, so a crew carries tents, food and fuel. Camping in the cold, with fewer chances to rest properly and little or no phone signal, makes a trek harder even when the trail itself is not.

Steps and trail surface

Nepal's middle hills are full of stone staircases. Our Annapurna Base Camp page calls the steps around Chhomrong "relentless", and our Langtang Valley page notes long stretches of steps on the way up. Descents are hard on the knees. Higher up you meet scree, moraine and, on a few routes, glacier.

Our four grades, in plain terms

Each trek on xTrekka carries one of four grades. We do not set them by formula, so we checked what they mean in practice by comparing the treks in each grade. Here is what we found.

Easy

• Highest point: 2,546–3,880 m.
• Length: 4–10 days.
• No high pass, and no night at or above 4,000 m.
• Longest walking day: about six to seven hours.
• Teahouse or homestay nights on almost every route, and no restricted-area permit.

These treks suit a first trip if you are reasonably fit and used to a day's hill walking. The Everest View trek is the one to treat with care: it is graded easy, but it flies you into Lukla at 2,860 m and sleeps above 3,000 m within two days.

Moderate

• Highest point: 3,350–4,773 m.
• Length: 5–14 days.
• No big pass. Passes, where there are any, are low ones such as the Pangsang La on the Ganesh Himal trek, or the passes of Upper Mustang, which stay below about 4,300 m.
• Overnights: at most one night at or above 4,000 m.
• Longest walking day: six to nine hours.

These are proper mountain treks, but without a big pass day or a long stay at high altitude. Upper Mustang is the long one: two weeks in a dry, windy, remote valley, with a restricted-area permit, but never high enough to sleep at 4,000 m.

Hard

• Highest point: 4,610–5,644 m.
• Length: 9–28 days.
• Fifteen of the nineteen cross a named high pass, from the Lauribina La to the Thorong La and the three Everest passes. The other four climb to a high viewpoint or base camp, such as Gokyo Ri at 5,357 m or Kala Patthar above Everest Base Camp.
• Longest walking day: seven to ten hours.
• Nine are in restricted areas, which need a special permit and, often, camping.

Extreme

Only one trek has this grade: the Tashi Lapcha Pass. It crosses a glacier pass at 5,755 m between the Rolwaling valley and the Khumbu. Our page describes a team carrying camping and climbing equipment, and the trek is fully camping from Tsho Rolpa until the descent to Thame. This is a mountaineering-style trip, not a trek for someone building up experience.

All 34 treks by grade

Days are the trip lengths shown on each trek page. Max altitude is the highest point of the route, which is often a pass, summit or viewpoint rather than where you sleep. Restricted means a special permit arranged through a registered agency; our trekking permits guide has the costs.

Easiest treks for a first trip

If this is your first trek in Nepal, start low and short. Good choices from the table:

• Ghorepani Poon Hill: four to seven days from Pokhara, a sunrise viewpoint at 3,210 m and busy lodge villages. Expect a lot of stone steps.
• Helambu: starts on the edge of Kathmandu, needs no flight and tops out at about 3,640 m. Our page calls it a common first trek.
• Tamang Heritage Trail: village homestays and culture rather than big peaks, staying below 3,200 m.
• Sikles: the lowest trek we list, though facilities above the village are basic.

For a first taste of real altitude without a pass, the moderate Mardi Himal, Annapurna Base Camp and Langtang Valley treks are the usual next step. All three are under two weeks and use lodges. The Annapurna and Langtang region pages list the rest.

Big passes for experienced trekkers

Once you have done a teahouse trek above 4,000 m and know how your body handles altitude, the pass treks open up:

• Annapurna Circuit: the classic. The Thorong La day is long, but lodges run the whole way.
• Manaslu Circuit: quieter, restricted, with the Larkya La on an eight-to-ten-hour day. See the Manaslu region.
• Gosainkunda Lake or Lauribina Pass: a pass of about 4,610 m, with both ends reachable by road from Kathmandu.
• Tilicho Lake: adds a high lake and a scree traverse to the Thorong La.

The hardest routes

These are the treks that combine height, length and remoteness:

• Everest Three Passes: three passes, and ten nights above 4,000 m on our itinerary. Our page asks for previous multi-day experience at altitude. See the Everest region.
• Upper Dolpo and Dolpo and Mustang: three weeks or more, at least two passes above 5,000 m and long camping stretches. Our Upper vs Lower Dolpo guide compares the two Dolpo routes, and the Dolpa region page lists them all.
• Makalu to Kanchenjunga: the longest trek we list, with overgrown trail in places and few places to resupply. See the Makalu and Kangchenjunga regions.
• Tashi Lapcha Pass: the only extreme trek, with glacier travel and climbing equipment.

How to get fit for a Nepal trek

You don't need to be an athlete. You do need to be comfortable walking for most of a day, then getting up and doing it again. Our Everest Base Camp page puts it simply: a willingness to walk five to seven hours on consecutive days.

A sensible plan, in the months before you go:

1. Walk long days back to back. A weekend of two full days on your feet, carrying the daypack you will use, tells you more than any gym session.
2. Train for the descent as well as the climb. Hill days with long downhill sections prepare your knees and thighs for the steps. Stairs work if you live somewhere flat.
3. Break in your boots on those walks, not on the trail.
4. Build up gradually, and see a doctor before booking if you have a heart or lung condition or other health concerns.

Remember the limit of fitness. It makes the walking more comfortable, but it does not stop altitude illness. A slow, steady ascent does that.

How a licensed guide changes the difficulty

A good licensed guide cannot make a pass lower, but they make the whole trip easier to manage:

• Pace. They set a pace you can hold all day, and slow you down on the way up, which is when most people go too fast.
• Acclimatisation. They keep the rest days in the plan and know where the side trips are that help you adjust.
• Route options. They know the lower variants, the bad-weather alternatives and when to turn back. Our Annapurna Circuit page describes the guide deciding the start time on Thorong La morning and turning the group back if the weather or anyone's health says so.
• Porters. With a porter or porter-guide carrying the main bag, you walk with a daypack, which makes long days far easier.

On most of the routes we list, a licensed guide is required anyway. Our post on whether you need a guide in Nepal explains the rules, and how much a trekking guide costs covers the prices. For season planning, see the best time to trek in Nepal.

Finding a guide

Every guide on xTrekka has had their trekking licence and citizenship document checked by our team before their profile goes live. Browse guides by region and language, read reviews from trekkers they have led, and write to them directly. Tell them your experience and fitness honestly, and ask which trek and pace they would suggest. You agree the route, dates and price with the guide, and xTrekka takes no cut of a trek you arrange directly with a guide.
