Overview
The Manaslu Circuit and Tsum Valley trek is a sixteen-day teahouse journey from Kathmandu that pairs the full circuit of Manaslu, the world's eighth-highest peak, with a detour into Tsum, a sacred hidden Buddhist valley tucked against the Tibet border. From the road-head at Machha Khola you climb the Budhi Gandaki gorge, branch off to Tsum for its old gompas at Mu and Rachen, then rejoin the main valley for Namrung, Samagaon and Samdo before crossing the Larkya La at 5,106 metres and descending to Dharapani. It is a restricted-area trek: the permit is issued only through a registered agency, with a licensed guide, and since 22 March 2026 solo travellers can also be issued the permit. The trails are remote, culturally rich and steadily high. This version begins and ends with the long drives from Kathmandu, so it suits trekkers basing themselves in the capital.

Good to know
Complete guide
The Manaslu region is one of Nepal's great circuits, and adding the Tsum Valley turns it into something rarer still: a full loop of an eight-thousander combined with a detour into a sacred, long-hidden valley. Doing it from Kathmandu means the long drives at each end are built in, so you start and finish in the capital. Here is how the trek works and what to know before you go.
What the Manaslu Circuit and Tsum Valley trek covers
The route runs from the Machha Khola road-head up the Budhi Gandaki gorge, branches off at Lokpa into the Tsum Valley for its monasteries at Mu and Rachen, then rejoins the main valley through Deng, Namrung, Samagaon and Samdo before crossing the Larkya La at 5,106 metres and dropping to Dharapani for the drive home. The first and last days are travel by road; the heart of the trip is around twelve days of teahouse walking. If you want the circuit without the Tsum detour, the shorter Manaslu Circuit trek from Kathmandu follows the same main valley and pass in fewer days.
Permits, guides and the restricted-area rules
Manaslu and Tsum are both restricted areas, which shapes how the trek is done. You need a separate restricted-area permit for each valley, plus the Manaslu Conservation Area permit and the Annapurna Conservation Area permit for the final descent. These permits are issued only through a registered agency, with a licensed guide. Since 22 March 2026 a solo traveller can also be issued the permit, so you can come alone. A licensed guide walks with you on every trek we run. We handle the paperwork and the guide; you bring your passport and passport photos.
Crossing the Larkya La and how the altitude feels
The Larkya La at 5,106 metres is the crux of the trek. The itinerary builds towards it slowly, with an acclimatisation hike to Manaslu Base Camp from Samagaon, before a short day up to the high camp at Dharmasala. Crossing day is long and cold, usually begun before dawn, and rewards you with a wide panorama of surrounding peaks before a steep descent to Bimthang. The gradual height gain keeps serious altitude sickness uncommon, but the air is thin up high, so walk slowly, hydrate and treat any symptoms seriously.
Tsum Valley and how it compares to other circuits
Tsum is what sets this trek apart. Sealed off from outsiders until recent decades, it remains a devout Buddhist valley of gompas, nunneries and mani walls, with a quiet, protected atmosphere that the busier trails have lost. Combined with the Manaslu circuit it makes for a long, remote and culturally deep trek. If you enjoy a big loop over a high pass but want something more established underfoot, the classic Annapurna Circuit trek from Pokhara crosses the Thorong La on well-served trails and works well as a next step or an easier alternative.
