Tsum Valley
A restricted-area trek that combines Himalayan village life, Buddhist heritage, and quieter trails in northern Gorkha.
Tsum Valley Trek takes you into the Tsum area of northern Gorkha District, close to the Tibetan border and inside the Manaslu Conservation Area. According to the National Trust for Nature Conservation, the Tsum area includes Chumchet and Chhekampar wards of Tsumnubri Rural Municipality, and the wider conservation area covers 1,663 square kilometers.
A common trek itinerary is around 16 days, beginning from Kathmandu, driving toward the lower Budhi Gandaki valley, and then branching from the main Manaslu trail toward Lokpa and Tsum. On the upper route, many trekkers overnight at Chumling (2,386 m), Chhokang Paro (3,031 m), and Nile (3,361 m), with Mu Gompa (3,700 m) as one of the best-known high points.
Nepal's Department of Immigration classifies Tsum Valley as a restricted trekking area. That means trekkers must go through an authorized trekking agency, must be accompanied by a licensed guide, and cannot obtain the restricted-area permit as a solo FIT trekker. Immigration also requires a minimum of two trekkers for the restricted permit.
Nepal Tourism Board lists the best season for the Manaslu Conservation Area as March to May and September to November, with both lodges and camping used in the region. If you want a trek centered on culture, monasteries, and a more peaceful pace than Everest or Annapurna, Tsum Valley stands out for exactly that reason.
