Trekking in the Monsoon Season in Nepal
Monsoon trekking means wet trails, leeches and hidden peaks — but green hills, low prices and dry rain-shadow options.
Trekking in Nepal's monsoon (June to early September) is the hardest season, but it is not impossible — and for the right route it can be rewarding. Across most of the country, expect wet trails, leeches, muddy paths and peaks lost in cloud, plus the risk of landslides and flight delays. The upsides are lush green hills, quiet trails and the lowest prices of the year. The key is choosing where you go. This page is part of our Nepal trekking seasons collection.
What the monsoon is really like
The summer monsoon brings warm, humid weather and heavy, often afternoon, rainfall to southern and central Nepal. On lower forested trails, leeches emerge in the damp, paths turn to mud, and rivers swell. Mountain views are unreliable as cloud builds through the day, though mornings can offer windows of clear sky. Roads and small mountain flights, including to Lukla, are more prone to weather disruption than in the dry seasons.
The downsides to plan for
- Leeches on lower, forested trails — carry salt or repellent and gaiters.
- Mud and slippery footing, with a higher chance of trips and falls.
- Clouded peaks, so high panoramas are unreliable across most regions.
- Landslides and flight delays, which can disrupt itineraries.
The upsides
For all its challenges, the monsoon has genuine appeal. The hills are at their greenest, terraced fields are vivid, wildflowers bloom, and waterfalls run full. Trails are blissfully quiet after the autumn crush, and lodge prices fall to their lowest. For travellers who value solitude and savings over guaranteed views, it has a real charm — the opposite experience to the crowded autumn peak season.
Where to go instead
If you want to trek in summer with the best odds of dry weather and clear days, head north of the main Himalaya to the rain-shadow regions — Upper Mustang, Dolpo and Nar Phu — which stay arid through the monsoon. Our dedicated guide to rain-shadow treks for the monsoon covers these dry routes, their scenery and the restricted-area permits they require.
Planning a monsoon trek
If you do trek in the wet season, choose your region carefully, build in buffer days for delays, and pack proper rain protection, quick-drying layers and leech defences. Altitude risk applies as in any season — read our altitude sickness in Nepal guide and plan kit, permits and pacing with the Nepal trekking guide.

Frequently asked questions
Can you trek in Nepal during the monsoon?+
Yes, but it is the most challenging season. From June to early September most trails are wet, muddy and leech-prone, peaks are usually hidden by cloud and landslides can disrupt roads and flights. The exception is the rain-shadow regions north of the main Himalaya, which stay dry and walkable.
What are the downsides of monsoon trekking?+
The main drawbacks are leeches on lower forested trails, slippery and muddy paths, clouded mountain views, swollen rivers, and a higher risk of landslides and flight delays. Mornings can be clearer before the afternoon clouds and rain build, but high panoramas are unreliable across most regions.
Are there any advantages to trekking in the monsoon?+
Yes. The hills are at their lushest and greenest, wildflowers bloom, trails are quiet and lodge prices are the lowest of the year. For trekkers who pick the right route — especially the dry rain-shadow valleys — the monsoon offers solitude and savings that the peak seasons cannot.
Where should you trek during the monsoon in Nepal?+
Head for the rain-shadow regions: Upper Mustang, Dolpo, Nar Phu and the upper Annapurna Circuit beyond Manang. These valleys sit behind the high Himalaya and stay largely dry, making them the best monsoon trekking choices while the rest of Nepal is soaked.
