Tsum Valley Trek Guide

Overview

The Tsum Valley trek is one of Nepal's great secrets — a restricted, lightly-trodden journey into a sacred Himalayan world that stayed closed to outsiders until 2008. Known in Tibetan as Beyul Kyimolung, the "hidden valley of happiness", Tsum is a deeply Buddhist enclave in the upper Budhi Gandaki, tucked against the Tibetan border in the Manaslu region of Gorkha district, Gandaki Province. Where the Annapurna Base Camp and Everest trails carry crowds, here you walk for days through villages that feel little changed in centuries.

The route branches off the famous Manaslu Circuit, climbing the Budhi Gandaki gorge before turning north-east at Lokpa into the Tsum Valley proper. From the lower settlement of Chumling the valley opens dramatically beneath Ganesh Himal and Sringi Himal, leading to the upper villages of Chhokangparo and Nile, and finally to the cluster of monasteries at the head of the valley: Mu Gompa (around 3,700 m), the largest in the region, and the Rachen Gompa nunnery below it. Pilgrims come here for Milarepa's Cave (Piren Phu), where the great Tibetan yogi is said to have meditated.

What sets Tsum apart is its living culture. The valley follows the shagya tradition of non-violence — killing animals is forbidden by long-standing communal vow — and the people are ethnically Tibetan, speaking their own dialect and keeping a calendar of festivals, mani walls, chortens and prayer flags that fill the trail. The walking is generally moderate to moderately strenuous: long approach days up the gorge, but a high point that is gentle compared with the great base-camp treks, topping out around Mu Gompa rather than crossing a serious pass.

Most trekkers complete Tsum in 14 to 18 days, sleeping in basic teahouses and family homestays, and many combine it with the full Manaslu Circuit for a longer journey of three weeks or more. It is the ideal trek for those who want culture, quiet and atmosphere over extreme altitude — a walk into one of the last hidden valleys of the Himalaya.

Day-by-Day Itinerary

This is a classic Tsum Valley itinerary that drives in from Kathmandu to the Manaslu roadhead, climbs the Budhi Gandaki, explores the upper valley around Mu Gompa, then returns the same way. Fit groups can shorten it slightly, and many trekkers extend it by continuing onto the full Manaslu Circuit instead of retracing their steps.

Day 1 — Drive Kathmandu to Soti Khola / Machha Khola (700-870 m)

A long, scenic but rough drive west and north from Kathmandu through Arughat to the Manaslu roadhead at Soti Khola or, road conditions allowing, on to Machha Khola. (7-9 hours by jeep.)

Day 2 — Machha Khola to Jagat (1,340 m)

The trail follows the Budhi Gandaki upstream through the warm river gorge, crossing suspension bridges and passing the hot springs at Tatopani, to the stone village of Jagat, where the restricted-area permit is checked and registered. (6-7 hours.)

Day 3 — Jagat to Lokpa (2,040 m)

A day of steady climbing along the gorge past Salleri and Philim, where the Tsum trail branches away from the main Manaslu route, turning north-east to the small settlement of Lokpa, the gateway to the hidden valley. (5-6 hours.)

Day 4 — Lokpa to Chumling (2,386 m)

The path drops and climbs through pine and rhododendron forest along the dramatic Tsum gorge, with first glimpses of Ganesh Himal, to the lower Tsum village of Chumling with its old gompa and mani walls. (4-5 hours.)

Day 5 — Chumling to Chhokangparo (3,010 m)

The valley widens as you cross to its eastern side and climb into upper Tsum, reaching the twin settlement of Chhokangparo, with sweeping views of Ganesh Himal and Himalchuli. (5-6 hours.)

Day 6 — Chhokangparo to Nile (3,361 m), visiting Milarepa's Cave

A culturally rich day past Lamagaon and the turn-off to Milarepa's Cave (Piren Phu), one of the holiest pilgrimage sites in the valley, before continuing through Phurbe to the upper village of Nile near the head of the valley. (5-6 hours.)

Day 7 — Nile to Mu Gompa (3,700 m)

A shorter, atmospheric climb up the increasingly barren, Tibetan-feeling upper valley to Mu Gompa, the largest monastery in Tsum, set close to the Tibetan border with the Ngula Dhojhyang pass area beyond. (3-4 hours.)

Day 8 — Exploration day at Mu Gompa

A day to explore the head of the valley: visit Mu Gompa and the nearby Dhephyudonma Gompa, hike higher toward the border for views, or simply absorb the silence of one of the most remote inhabited corners of Nepal. A rest and acclimatisation day.

Day 9 — Mu Gompa to Rachen Gompa / Chhokangparo (3,240 m)

Descend the valley, crossing to visit the Rachen Gompa nunnery — one of the largest in the region — and its community of nuns, before continuing down toward Chhokangparo. (5-6 hours.)

Day 10 — Chhokangparo to Chumling (2,386 m)

Retrace the trail down through upper and lower Tsum, with the mountains now behind you, returning to Chumling. The downhill return is quicker than the climb. (5-6 hours.)

Days 11-13 — Chumling to Lokpa, Jagat and Machha Khola

Descend out of the Tsum gorge to Lokpa, rejoin the Budhi Gandaki, and follow the river back down through Jagat to Machha Khola, retracing the approach in reverse over two to three trekking days.

Day 14 — Drive Machha Khola / Soti Khola to Kathmandu

A long jeep drive back down the valley and along the road to Kathmandu. Build in a contingency day, as monsoon-season landslides and rough roads can cause delays.

Difficulty & Fitness

The Tsum Valley trek is graded moderate to moderately strenuous. It is gentler than the great base-camp treks because the high point — around Mu Gompa at roughly 3,700 m — is far lower than Everest or Makalu Base Camp, and there is no major pass to cross on the standard out-and-back route. What makes it demanding is the distance and the terrain rather than the altitude.

• Long approach days. The climb up the Budhi Gandaki gorge involves several long days on a trail that rolls steeply up and down between river crossings, with sustained ascents into the valley.
• Remoteness. This is a restricted, lightly-served region. Lodges are basic and sparse, supplies are limited, and there is no quick road bailout once you are deep in the valley.
• Moderate altitude. You sleep around 3,000-3,700 m in upper Tsum. Altitude sickness is less of a concern than on the high treks, but it is not negligible, and a built-in rest day helps.
• Basic facilities. Accommodation is in simple teahouses and family homestays, with plain food and few comforts.

You should be comfortable walking 5-7 hours a day on rough trails for two weeks or more. No technical skills are needed, but reasonable fitness and some hill-walking experience make the long gorge days far more enjoyable. Train with loaded day-pack hikes and stair or hill repeats for a few weeks beforehand.

Permits & Regulations

Tsum Valley is a restricted area, so the paperwork is stricter than on the open trekking routes. You need three documents:

• Tsum Valley Restricted Area Permit (RAP) — around USD 40 per person per week in the high season (September-November) and USD 30 per week in the rest of the year (December-August). It is issued only through a registered trekking agency.
• Manaslu Conservation Area Project (MCAP) permit — around NPR 3,000 for foreign nationals, covering the conservation area you pass through.
• Annapurna Conservation Area Project (ACAP) permit — around NPR 3,000, needed only if you combine Tsum with the full Manaslu Circuit and exit through the Annapurna conservation area.

Crucially, the restricted-area rules mean there is no solo trekking: you must travel with a government-registered guide and in a group of at least two trekkers, arranged through a registered agency that lodges the permits on your behalf. Carry your passport and several passport photos, and keep permits handy for the checkpoints at Jagat and beyond. Regulations and fees change periodically, so confirm the current requirements with a registered agency or the Nepal Tourism Board before you travel.

Cost & Budget

Tsum is more expensive than the open teahouse trails, mainly because the restricted-area permit, the mandatory guide and the minimum-group rule all add to the cost, and because supplies must be carried into a remote valley.

• Guided package: typically USD 1,200-2,200 per person depending on group size and the number of days. This usually covers the guide, porters, all permits, ground transport from Kathmandu, accommodation and meals on the trek.
• Permits: the Tsum Restricted Area Permit (around USD 40 per week in autumn, USD 30 per week otherwise), plus the MCAP permit (around NPR 3,000) and, if combining with Manaslu, the ACAP permit (around NPR 3,000).
• Transport: the long jeep drives between Kathmandu and the Soti Khola / Machha Khola roadhead at each end.
• On-trail spending: carry enough Nepali rupees in cash for the whole trek — there are no ATMs in the valley, and you will need cash for extras, tips, charging, hot showers and any teahouse purchases.

Larger groups bring the per-person price down, since the guide and permit costs are shared. A generous tip for guides and porters is customary. Budget a contingency for rough roads and possible delays.

Best Time to Trek

There are two clear trekking seasons for Tsum Valley, and choosing the right one matters because of the deep, landslide-prone Budhi Gandaki gorge.

• Autumn (September-November) is the prime window: stable weather, clear skies, sharp views of Ganesh and Sringi Himal, and firm trails after the monsoon. This is also when several Tibetan Buddhist festivals can fall in the valley.
• Spring (March-May) brings warmer days, rhododendron blooms on the lower trail and generally good visibility, though some afternoon haze is possible.

Avoid the monsoon (June-early September): the gorge is prone to landslides, the trail is slippery, and the lower forest is thick with leeches and cloud. Deep winter (December-February) is very cold in the upper valley around Mu Gompa, with some teahouses closed and the high settlements bitter; while it is walkable, most trekkers prefer the two main seasons. For the best balance of weather, views and culture, plan for autumn or spring.

Packing, Safety & Tips

Acclimatisation

Tsum's high point of around 3,700 m is modest by Himalayan standards, but you still gain altitude steadily through the upper valley. Ascend at a sensible pace, keep the rest day at Mu Gompa, stay hydrated, and watch for any headache, nausea or dizziness. Serious altitude sickness is uncommon here, but the valley is remote, so do not ignore symptoms.

Gear & packing

Pack for a cool-to-cold mountain trek: a warm sleeping bag, a good down or insulated jacket, layered clothing, sturdy broken-in boots, trekking poles, sun protection and a headlamp. Because facilities are basic, bring a reliable water-purification method, snacks, and a first-aid kit including blister care. For the wet, leech-prone lower gorge in the shoulder seasons, pack leech protection and waterproofs.

Respecting the culture

Tsum is a living sacred landscape. Walk clockwise around chortens, mani walls and prayer wheels, dress modestly, ask before photographing people or monastery interiors, and respect the valley's shagya tradition of non-violence — meat is rarely available and hunting or killing animals is forbidden by local vow. A small donation at the gompas you visit is appreciated.

Communications & money

Phone signal is patchy to non-existent for much of the valley, and there is no electricity grid in places — charging is often by solar and may carry a fee. There are no ATMs on the route, so carry enough cash in Nepali rupees for the entire trek plus a buffer.

Safety, guides & insurance

Restricted-area rules require a licensed guide and a minimum group of two through a registered agency, which also handles the logistics of this remote region. Buy comprehensive travel insurance that explicitly covers trekking and includes helicopter evacuation, as a rescue from the upper valley is slow and expensive without cover.

Combining with other treks

Tsum Valley is most often combined with the full Manaslu Circuit, since both share the Budhi Gandaki approach and the same permit system — together they make a magnificent journey of around 21 days or more, adding the Larkya La pass to Tsum's cultural depth. If you want a contrast in style afterwards, the classic lodge trails of the Annapurna Base Camp region or the wilder Makalu Base Camp trek offer very different experiences. Base yourself in Kathmandu before and after to arrange permits, guides and gear.
