Best Time to Trek in Nepal: A Clear Season Guide

Nepal Trekking Season at a Glance

Here is a quick look at all four seasons:

Trekking Seasons in Nepal

Nepal has four main trekking seasons. Each one is very different. Here is what to expect from each.

Spring (March to May)

Spring is one of the two best times to trek. Days are warm. Skies are clear. Red and pink flowers cover the hillsides.

Temp: 5°C to 18°C at mid-altitude. High camps drop below -10°C at night.

Views: Clear in March and April. Some haze can build by late May.

Crowds: High. Book your permits and beds early.

Why go in spring:

• Red rhododendron forests bloom along most trails
• All high passes are open and safe
• Good light for photos in the morning
• Long days give more time to hike

Watch out for:

• Trails are busy, especially in April
• Beds fill fast at busy stops
• Late May can get hazy in the afternoon

Best trails: Everest Base Camp, Annapurna Circuit, Annapurna Base Camp, Langtang Valley, Gokyo Lakes.

Safety tip: UV rays are strong at high altitudes. Wear sun cream and good glasses.

Autumn (September to November)

Autumn is the most popular season. It is also the best one. The monsoon ends, and the skies clear fast. Views are sharp. The air is clean.

Temp: 5°C to 20°C at mid-altitude. Nights at base camp are -5°C to -10°C.

Views: The best of the whole year. October skies are almost always clear.

Crowds: Very high in October. Trails can feel packed on the main routes.

Why go in autumn:

• October has the clearest skies of the year
• Green hills from the monsoon rain look great in photos
• All high passes and far routes are open
• Good for all skill levels

Watch out for:

• Very high-demand books are in high demand months in advance
• Prices are at their peak
• Late November gets cold. Days get short.

Best trails: All main routes. Everest Base Camp, Annapurna Base Camp, Annapurna Circuit, Langtang, Gokyo, Mardi Himal.

Safety tip: Cold nights need a good sleeping bag. Snow can fall on high passes in November.

Winter (December to February)

Winter is a hidden gem. Most people skip it. But skies are clear, and trails are quiet. Costs drop a lot. It works well for low-altitude routes.

Temp: -10°C to 10°C at mid-altitude. Very cold at high camps.

Views: Clear and bright on most days.

Crowds: Very low. You may have trails all to yourself.

Why go in winter:

• Prices drop 20 to 40 percent
• Trails and tea houses are quiet
• Great for Poon Hill, Ghorepani, and lower Langtang
• Clear skies give good mountain views

Watch out for:

• High passes can be blocked by snow
• Some tea houses at high altitudes close
• Cold at night. Pack warm gear.

Best trails: Poon Hill, Ghorepani, lower Langtang, Upper Mustang.

Safety tip: Cold at high altitude is a real risk. Go with good gear. Be ready for delays.

Monsoon (June to August)

The monsoon brings heavy rain. Most trails get muddy and wet. Leeches come out on low paths. Views are blocked by clouds most days. Most people skip this season.

Temp: 15°C to 25°C at mid-altitude. Hot and humid on low trails.

Views: Poor on most routes. Clouds hide the peaks.

Crowds: Very few trekkers. Rain-shadow zones are quiet but not empty.

Where to go: Upper Mustang, Dolpo, Nar Phu, Tsum Valley. These areas sit behind high ridges. The monsoon rain barely reaches them.

Safety tip: Floods and landslides are real risks. Get travel insurance with rescue cover.

Best Time to Trek by Region

Everest Region (Khumbu)

Trek Everest Base Camp in October or April. These are the safest months. October has the clearest skies. Spring is best for climbers on the big peaks. Winter trekking to EBC is possible. But it is cold and needs skill. Avoid the monsoon, trails are risky, and views are blocked.

→ See our Everest Base Camp Trek page for permits, routes, and costs.

Annapurna Region

The best months are October and April. The Thorong La Pass (5,416m) is safest in these months. Snow can block the pass in late November or late May. The Poon Hill route is fine in winter for fit trekkers.

→ See our Annapurna Base Camp Trek page for the full route guide.

Langtang Region

Langtang works well in spring and autumn. Winter is fine on the lower trail. The valley gets less monsoon rain than Annapurna. Late August can work for those who have done it before. Gosaikunda Lake is best in autumn.

Upper Mustang and Dolpo

These two areas are special. They stay dry even in the monsoon. They sit on the Tibetan plateau. Rain barely falls here. You can trek from May to October. The monsoon months are great here when other trails are wet. You need a special permit and a guide.
