Trekking Season in Nepal

The Best Trekking Seasons in Nepal:

Nepal is a small country in South Asia, but rich in cultural and Natural diversity. It is the home to the majestic Himalayas, sitting at the most of the world’s highest mountains on the northern border of the country. The soaring Himalayas offer some of the world’s most iconic trekking and expedition routes. Some of the very famous trekking routes are Everest Base Camp, Three Pass Trek, Gokyo Valley Trek, Annapurna Base Camp Trek, Annapurna Circuit Trek, Nar Phu Valley Trek, Upper Mustang, Langtang Valley Trek, Manaslu Circuit Trek, and Many More. Every year, thousands of backpackers, trekkers, researchers, and adventure lovers visit this beautiful country and enjoy the diversity. While trekking is possible year-round, the best seasons are spring (March to May) and autumn (September to November) due to stable weather, clear skies, and comfortable temperatures. Other seasons, like winter and rainy, are not ideal for a high pass trek, but it is still possible at the lower elevation in winter and the rain shadow region, like Upper Dolpo and Upper Mustang, in the rainy season.

Spring Season (March to May)

Temperature:

  • Day: 16°C to 30°C (in lower regions)
  • Night: 5°C to -5°C (in higher altitudes)

Spring is one of the most popular trekking seasons in Nepal. As the snow begins to melt and temperatures rise, trails become accessible and the landscape bursts into color. Rhododendrons, Nepal’s national flower, bloom along the mid-hill trails, offering a vibrant trekking experience. Temperatures are moderate, especially at lower elevations, and visibility is generally excellent, making it ideal for panoramic mountain views. At the high elevation, you can witness the wild flowers and stunning views where wild flowers and snowcapped peaks meet.

Popular treks during spring are:

  • Everest Base Camp Trek
  • Three Pass Trek
  • Annapurna Circuit Trek
  • Annapurna Base Camp Trek
  • Ghorepani-Poon Hill Trek
  • Manaslu Circuit Trek
  • Kanchenjunga Trek
  • Upper Mustang and Dolpo Trek

Spring is also great for high-altitude treks, as the weather is relatively dry and warm compared to winter.

Autumn Season (September to November)

Autumn is widely considered the best season for trekking in Nepal. After the monsoon rains (June to August), the air is crisp, the skies are crystal clear, and the mountains appear at their most photogenic. The weather is stable, with mild days and cooler nights, making it ideal for long trekking days and scenic views.

Autumn is also culturally rich, coinciding with major Nepalese festivals like Dashain and Tihar, offering trekkers a chance to experience local traditions and celebrations along the way.

Temperature:

  • Day: 15°C to 24°C (moderate at mid altitudes)
  • Night: 5°C to -5°C (in higher altitudes)

Top treks for autumn include:

  • Everest Base Camp Trek
  • Two Pass Trek
  • Three Pass Trek
  • Gokyo Valley Trek
  • Annapurna Base Camp Trek
  • Annapurna Circuit Trek
  • Nar Phu Valley Trek
  • Langtang Valley Trek
  • Upper Mustang (especially after the rain-washed scenery)

Summer/Monsoon Season (June to August)

Temperature:

  • Day: 20°C to 30°C (in lower regions)
  • Night: 10°C to 15°C
  • Higher altitudes remain cooler: 1°C to 10°C

The monsoon brings heavy rainfall, especially in the central and eastern parts of Nepal. Trekking during this season is challenging due to slippery trails, leeches, landslides, and poor visibility. However, it’s also the time when Nepal’s landscapes are at their greenest.

Some regions like Upper Mustang and Dolpo fall in the rain shadow of the Himalayas and remain relatively dry, making them suitable for trekking even during the monsoon.

Best Trekking and travel routes:

  • Upper Mustang Trek,
  • Upper and Lower Dolpo Trek
  • Nar Phu Valley Trek
  • Annapurna Circuit Trek
  • Chitwan Safari Tour

Winter Season (December to February)

Temperature:

  • Day: 9°C to 15°C (lower elevations)
  • Night: -5°C to -15°C (higher altitudes)

Winter brings cold temperatures, especially in the mountains, but skies are often clear and the air is crisp. Snowfall may block some high passes like Thorong La or Cho La, but lower elevation treks remain accessible and peaceful with fewer trekkers.

For those seeking solitude, winter offers quiet trails and scenic beauty. Proper gear is essential, especially for high-altitude routes.

Best treks in winter:

  • Ghorepani-Poon Hill Trek
  • Helambu Trek
  • Chisapani-Nagarkot Trek
  • Pikey Peak Trek
  • Langtang Valley Trek
  • Tsum Valley Trek
  • Everest Panorama Trek
  • Mardi Himal Trek

Nepal offers incredible trekking opportunities throughout the year, but the best seasons are clearly spring (March–May) and autumn (September–November). These months provide the best combination of weather, visibility, trail conditions, and cultural richness. Choose the right season for the perfect Trekking experience in Nepal.
