Best Time to Trek in Nepal: A Season-by-Season Guide

Nepal's trekking calendar isn't one-size-fits-all — the right season depends heavily on which region you're heading to. Here's how our guides plan departures across the year.

Spring (March–May)

Widely considered the best all-round trekking season. Daytime temperatures are pleasant, mountain visibility is generally excellent, and rhododendron forests bloom spectacularly along routes like Poon Hill, Annapurna Base Camp and Mardi Himal. This is peak season for Everest Base Camp, Annapurna Circuit and Manaslu.

Autumn (September–November)

The other prime season, following the monsoon when the air is freshly washed and skies are at their clearest for mountain photography. Trails and teahouses are busiest during this window, especially October, so book flights and lodges in advance.

Winter (December–February)

Lower-altitude treks like Ghorepani Poon Hill and Langtang Valley remain very trekkable, with clear skies and cold but manageable temperatures. High passes such as Thorong La or Larkya La can close after heavy snowfall, so winter is not recommended for the Annapurna Circuit or Manaslu Circuit.

Monsoon / Summer (June–September)

Most of Nepal is wet, leech-prone and often cloud-covered during monsoon — but the trans-Himalayan rain-shadow regions of Upper Mustang and Dolpo are the exception, staying dry and clear precisely when the rest of the country is under cloud. If you can only travel in summer, these two regions are your best options.

• Everest Base Camp & Annapurna Base Camp: March–May or September–November
• Annapurna Circuit & Manaslu Circuit: March–May or September–November
• Ghorepani Poon Hill & Langtang: year-round, best March–May and September–December
• Upper Mustang & Dolpo: June–September (rain shadow) or spring/autumn shoulder windows
