Manaslu Circuit & Tsum Valley Trek – 24 Days

Overview

Most treks give you one kind of experience — mountains, or culture, or remoteness. This one gives you all three, stacked together into a single 24-day journey. You’ll walk into Tsum Valley, a Tibetan Buddhist sanctuary so isolated it only opened to outside visitors in the early 2000s, then rejoin the Manaslu Circuit and cross Larkya La, one of the highest trekking passes in the Himalayas. It’s a genuinely complete picture of this corner of Nepal — not a highlight reel, the whole thing.

The trek starts the same way the standard Manaslu Circuit does, following the Budhi Gandaki River out of the lowlands near Kathmandu, through terraced rice fields and dense forest, crossing wooden suspension bridges that sway with every step. But instead of continuing straight up the valley, you’ll branch off toward Tsum — locally known as Beyul Kyimolung, the “Hidden Valley of Happiness,” a name rooted in Tibetan Buddhist tradition referring to a place of spiritual refuge. After days spent among its monasteries and villages, the trail rejoins the main Manaslu Circuit and climbs to Larkya La, with Mount Manaslu (8,163m), the eighth-highest mountain on Earth, as a constant presence for the second half of the trip.

Why Choose This Trek?

• The Manaslu Circuit — dramatic mountain landscapes circling the eighth-highest peak in the world.
• Tsum Valley — a culturally preserved valley shaped by centuries of Tibetan Buddhist heritage.
• Mu Gompa and Gumba Lungdang — remote monasteries well away from Nepal’s busiest trekking routes.
• Ganesh Himal Base Camp — a genuinely demanding side excursion into high mountain terrain.
• Larke-La Pass — one of the major high-altitude crossings in the Himalayas.
• Tibetan Buddhist culture throughout — monasteries, prayer walls, chortens, and villages that still live by it.
• Remote landscapes that keep changing — forest, river valley, glacier, alpine terrain, and high mountain scenery.
• Far fewer trekkers — a genuinely quiet alternative to Nepal’s more commercial routes.

What Makes This Trek Special?

Tsum Valley — The Cultural Heart Tsum stayed closed to outside visitors until relatively recently, and that isolation shaped everything about it. The Tsumba people who live here have their own distinct identity, shaped by centuries of contact with Tibet rather than the rest of Nepal. Villages like Chhokangparo and Nile sit surrounded by prayer flags and mani walls, with monasteries — some centuries old — still functioning as genuine centers of daily religious life, not tourist stops.

Manaslu Circuit — The Mountain Journey Once you rejoin the main circuit, the landscape shifts fast. Green terraced valleys and forest give way to sparse alpine vegetation, then bare rock and glacier as you climb toward Samagaon, Samdo, and eventually Larkya La itself. It’s one continuous transformation, not a series of separate stops.

Larke-La Pass — The Big Challenge Reaching the pass is one of the genuine physical achievements of this trek, not just a scenic waypoint. It’s a long, cold, early-morning climb over exposed, high-altitude terrain, and getting there successfully is something you’ll actually feel proud of, not just photograph.

Two Experiences, One Trek Doing Tsum Valley and the Manaslu Circuit together makes for a more complete journey than either route alone. Tsum gives you the cultural depth that the standard circuit only touches on in passing; the circuit gives you the high-altitude mountain drama that Tsum, on its own, doesn’t reach. Combined, you get both halves of what makes this whole region special, rather than having to choose.

Why Choose This Instead of Manaslu Circuit Only?

Choose the standard Manaslu Circuit if your priority is completing the circuit efficiently, in less time. Choose this Tsum Valley combination if you want the additional cultural depth — monasteries, remote villages, and a fuller experience of this whole region, not just its mountains.

Tsum Valley & Buddhist Heritage

This is the section of the trek that genuinely sets it apart, so it’s worth explaining what you’ll actually encounter, not just naming it.

Mu Gompa sits at 3,700m and is the largest and highest monastery in Tsum Valley — the natural turnaround point for most visitors, and a place where monks still maintain a daily routine of prayer largely undisturbed by outside visitors.

Gumba Lungdang is a remote nunnery with a genuinely striking origin story: it was founded in the early 20th century through the determined efforts of a blind man. Perched with a wide outlook over the valley, it’s also known among trekkers as one of the best sunset viewpoints anywhere in the Himalayas.

Rachen Gompa, established in 1905 in the Shiar Khola Valley, is another significant nunnery along the route, known for its murals and statues and a genuinely welcoming atmosphere.

Beyond the named monasteries, the whole valley is threaded with prayer walls you’re expected to pass on the left, hand-carved mani stones, weathered chortens marking trail junctions and village entrances, and prayer flags strung across nearly every pass and rooftop. The villages themselves — Tibetan-influenced in architecture, language, and daily rhythm — carry on largely as they have for generations, with traditional religious practice woven into ordinary life rather than set aside for visitors to observe.

A Day in the Life

In the lower valley: mornings start beside the Budhi Gandaki River, the trail weaving through forest and terraced fields, crossing wooden suspension bridges that sway underfoot with every step. It’s warm, green, and still feels like the foothills.

In Tsum Valley: the rhythm changes. Villages appear more often, each with its own small monastery or chorten. Prayer flags mark the trail constantly, and it’s common to pass local people going about ordinary business — farming, herding, walking to the next village — rather than posing for photos.

In upper Manaslu: vegetation thins out fast. Alpine terrain replaces forest, snow peaks dominate the skyline, and the air noticeably thins. Villages get smaller and further apart, and the pace of the trek slows to match the altitude.

On Larke-La day: an early, cold start — often before dawn — followed by a long, steady climb over increasingly exposed terrain. Reaching the top brings genuine relief and a wide, snow-covered panorama in every direction, before a demanding, equally long descent on the other side.

Trek Difficulty

This is a long, physically demanding trek — 24 days, high altitude, and one of the Himalayas’ more serious pass crossings. Daily walking runs 3-9 hours, with the Larke-La crossing and the Ganesh Himal Base Camp side trip being the two hardest single days.

Altitude. You’ll reach nearly 5,000m at Rui La and cross Larke-La above 5,100m, with an extended stretch of the trek spent above 3,500m. Acclimatization days are built in at Samagaon and around the Rui La side hike — take them seriously.

A note on Larke-La’s exact altitude: sources vary here, with some citing 5,106m and others (including this itinerary) using 5,160m. It’s worth confirming which figure Snow Bank wants to use consistently across its Manaslu-related pages.

A note on Ganesh Himal Base Camp: different operators use different figures for this stop, ranging from around 4,200m to 4,900m depending on the exact route and endpoint used. This itinerary lists 4,900m — worth double-checking against Snow Bank’s actual route before publishing, since it’s a meaningful difference for a trekker’s expectations.

Permits. You’ll need a Tsum Valley Restricted Area Permit, a Manaslu Restricted Area Permit, a Manaslu Conservation Area Permit (MCAP), and an Annapurna Conservation Area Permit (ACAP) for the final stretch through Dharapani. A licensed guide is mandatory throughout, though as of March 2026, Nepal no longer requires a minimum of two trekkers to obtain these restricted-area permits, so solo travelers can join with just their guide.

Best time to go. Spring (March-May) and autumn (September-November) offer the most stable weather for both Tsum Valley and the Larke-La crossing.
