The short version
Spring (March–May) is one of Nepal's two best trekking seasons — warm weather, blooming rhododendrons, and the Himalayan climbing season. Guide to spring conditions, the best treks, and what to expect.
- Spring (March–May) is one of Nepal's two prime trekking seasons, bringing warm weather, the rhododendron bloom, and the Himalayan climbing season.
- Late March to mid-April is the sweet spot for the rhododendron spectacle — entire hillsides of crimson, pink, and white blooms beneath the snow peaks.
- Best spring treks include Ghorepani Poon Hill, Mardi Himal, Annapurna Base Camp, Everest Base Camp, Langtang, and the Annapurna and Manaslu Circuits.
- Days are warm but nights at altitude stay cold — pack layers, and start early to beat the afternoon haze that builds later in spring.
Nepal's second peak season
Spring — March, April, and May — is one of Nepal's two prime trekking windows (alongside autumn). It brings warming weather, the famous rhododendron bloom, good mountain views, and the buzz of the Himalayan climbing season. Here's what to expect and the best treks to do. For year-round context, see our best time to trek in Nepal guide.
What spring is like
| Month | Conditions | Notes |
|---|---|---|
| March | Warming days, generally clear skies | Rhododendrons starting to bloom; high passes opening as snow melts |
| April | Peak spring — warm, good views, some afternoon haze | Rhododendrons in full colour; main climbing season in full swing |
| May | Warm to hot lower down, increasing haze | First pre-monsoon showers late month; excellent high up before the rains |
The rhododendron spectacle
Spring's signature is the bloom — entire hillsides of crimson, pink, and white rhododendron (Nepal's national flower) beneath the snow peaks. The forests of Poon Hill, Mardi Himal, Langtang, and the ABC route are spectacular. Late March to mid-April is the sweet spot. (See our rhododendron trek guide.)
Best treks in spring
Almost any trek works in spring, but these are the standouts:
Classic short trek through rhododendron forests with sunrise mountain panoramas.
Quieter ridge trek bursting with spring blooms and close Annapurna views.
Forested approach to a high amphitheatre of peaks, superb in spring.
Trek amid the buzz of the Everest climbing season as expeditions arrive.
Rhododendron-lined valley close to Kathmandu, lovely in spring.
High passes are generally open as the snow melts through spring.
Spring considerations
Days are warm and pleasant, but nights at altitude are still cold — pack layers and a good sleeping bag. Afternoon haze can build later in spring, so start early for the clearest mountain views. May's pre-monsoon heat and haze are the main downsides lower down. Book ahead — spring is peak season, second only to autumn.
Spring vs autumn
Autumn (Oct–Nov) has the crispest post-monsoon clarity; spring has warmth, blooms, and climbing-season energy but slightly more haze. Both are excellent. If you want rhododendrons and warmer trekking, choose spring.
The bottom line
Spring is a superb time to trek Nepal — warm, colourful, and lively, with good views and open high passes. Time it for late March to mid-April to catch the rhododendrons at their best, pack for cold nights despite the warm days, and book early for this popular season.

When is the best time to see rhododendrons in Nepal?
Late March to mid-April is the sweet spot. During this window, hillsides on routes like Poon Hill, Mardi Himal, Langtang, and the Annapurna Base Camp trail blaze with crimson, pink, and white rhododendron blooms.
Is spring or autumn better for trekking in Nepal?
Both are excellent. Autumn (October–November) has the crispest post-monsoon clarity, while spring (March–May) offers warmer weather, rhododendron blooms, and climbing-season energy but slightly more afternoon haze. Choose spring if you want flowers and warmer trekking.
