Manaslu Region Trek

The Manaslu region is the country around one mountain. Mount Manaslu (8,163M) is the eighth highest in the world and the highest point in the Gorkha district, and everything here, the trails, the villages, the permit rules, is arranged around it. Below is the region itself: the mountain, the conservation area that protects it, and the people who live inside the boundary. For the walking, see the Manaslu Circuit Trek guide and what it costs.

The Manaslu Region at a Glance

Mount Manaslu, the Mountain the Region Is Named For

The name comes from the Sanskrit manasa, meaning intellect or soul, and the mountain is often translated locally as "mountain of the spirit". At 8,163M it is the eighth highest in the world and the highest point in the Gorkha district, which is also where Prithvi Narayan Shah launched the campaign that unified Nepal. Walk here and you are in the country's founding ground as well as its high country.

A Japanese team made the first ascent in 1956, and Manaslu has been closely associated with Japanese mountaineering ever since. The trekking route around it only opened to foreigners in 1991, which is why the valley still feels less worked than Annapurna or Khumbu. Two generations of trekkers have walked those, and one has walked this.

Why Manaslu Is Called the Killer Mountain

You will see Manaslu called the killer mountain. That reputation belongs to the climb, not the trek.

It comes from the summit's fatality rate and from avalanche years such as 2022, all of it above 7,000M on an expedition route that has nothing to do with the trekking trail. Manaslu is dangerous to climb for the same reasons every 8,000M peak is: thin air, loaded slopes, and a summit day long enough that weather can change under you. It is not, on the numbers, the deadliest of them. Annapurna I and K2 are consistently worse.

The trekking circuit does not go near it. Larkya La at 5,106M is a walking pass, crossed by thousands of people a year without ropes, crampons or technical skill. If the name has put you off, it should not. The reasons this trek is hard are distance, altitude and remoteness, and those are covered honestly in the trek guide.

The Manaslu Conservation Area

Everything above Jagat sits inside the Manaslu Conservation Area, declared in December 1998 and covering 1,663 square kilometres of the Gorkha district, from about 600M in the lower valley to the summit at 8,163M. It is managed by the National Trust for Nature Conservation rather than by the government directly, which is why the MCAP fee on your permit goes to a trust and not a ministry.

That fee is the reason the valley looks the way it does. Roughly 9,000 people live inside the boundary, mostly Nubri and Tsumba, and the conservation model here funds their schools, health posts, trail repair and drinking water from trekking permits rather than fencing them out. It is community-led by design, because environmental protection in a valley with no road only works if the people living in it are better off for the rules.

Geography: The Mansiri Himal and the Budhi Gandaki

The conservation area lies within the Mansiri Himal range. It borders the Tibetan Plateau to the north, the Annapurna Conservation Area to the west and the Ganesh Himal to the east, and the ground rises from subtropical river valley to permanent snow inside a single day's walk in places.

The Budhi Gandaki is the main waterway. It flows about 150KM from the Tibetan border down the centre of the region, and the circuit follows it for most of the walk in. Between Jagat and Deng it runs through a gorge with high cliffs on both sides, which is the stretch of suspension bridges and cut rock stairways that people remember. West of Larkya La the Dudh Khola takes over, running down the Bimthang valley to join the Marsyangdi and connect this region to Annapurna.

Higher up, the Larkya and Pungyen glaciers cover the slopes. Birendra Lake (3,691M) sits below Manaslu Base Camp, turquoise with meltwater off the Manaslu Glacier, and is the standard acclimatisation walk from Samagaun. Kal Tal, the black lake above Prok village, is the one almost nobody visits.

Forests and Vegetation by Altitude

The region supports more than 2,000 species of flowering plants across roughly a dozen forest types, because the land climbs through so many climate zones at once.

Wildlife in the Manaslu Conservation Area

Official figures record 33 species of mammals and 110 species of birds inside the boundary, alongside reptiles and amphibians. Later surveys put the counts higher. The wide elevation range and the small human footprint are what keep species here that have gone from busier trekking regions.

Realistically, what a trekker sees is blue sheep above Samdo and Himalayan tahr on the steep ground lower down. Snow leopard and red panda live here and are almost never sighted. Birdwatchers should look for the Himalayan monal, Nepal's national bird, in the forest between Deng and Namrung.

The People of the Valley

Three communities live inside the boundary and they do not share a background. The lower valleys below Jagat are Gurung and Tamang, farming terraces of millet and maize. The upper Nubri valley around Lho, Samagaun and Samdo is ethnically Tibetan, settled in part by refugees who crossed the border above Samdo. Tsum Valley to the east is its own case again, with a Buddhist tradition older than the Nepali state.

Monasteries such as Pungyen Gompa on the glacier above Samagaun and Ribung Gompa at Lho still function, and mani walls line the trail into every village. The Tibetan character of the upper valley shows most clearly at Lhosar, the Tibetan new year, set by the Tibetan calendar rather than the Nepali one, so it usually falls in February. Walk here in late winter and you may meet it.

The cultural heritage is as much a reason for protection as the wildlife is, which is why the conservation rules ask visitors to treat these villages as homes rather than exhibits.

Climate by Altitude

Spring, March to May, and autumn, September to November, are the trekking seasons. Season choice by trek is covered in the guide.

Trekking Rules Inside the Conservation Area

• A licensed guide is compulsory. Every trekker walks with a government licensed guide from a registered agency, throughout the restricted area between Jagat and Dharapani.
• Group size. Since 22 March 2026 the Restricted Area Permit can be issued to a single trekker, so the old two-person minimum no longer applies. One guide may lead a maximum of seven.
• Permit and passport checks. Originals are shown at Jagat, Deng, Samagaun and Samdo. Digital copies are not accepted.
• Stay on the approved route. Entry into the border zones near Tibet is prohibited.
• No open fires, and carry your rubbish out. Single use plastic is discouraged throughout.
• Drones and professional filming need permission. Ordinary photography does not.

Permit types and 2026 prices are set out in full in the trek guide.

Getting to the Manaslu Region

There is no airstrip and no road inside the conservation area, so every trip starts with a drive. The trailhead at Machha Khola is about 160KM northwest of Kathmandu and takes 8 to 10 hours by road, paved as far as Arughat and rough after that. Public buses leave Gongabu early; a private jeep is faster and carries a group with its guide and porters.

You enter the conservation area on foot between Jagat and Deng on the second walking day, and leave it on the far side of Larkya La at Dharapani, where the Annapurna Conservation Area begins. Beyond Samagaun there is no vehicle access at all, which is why evacuation from the upper valley is by helicopter only.

Which Manaslu Trek to Choose

The three trips above use the same trailhead and the same three permits, and differ in what they add.

• Manaslu Circuit Trek. The full loop up the Budhi Gandaki and over Larkya La. The main route, and the reason most people come.
• Tsum Valley Trek. The side valley north east of Lokpa, monasteries and Tibetan culture, far quieter than the circuit.
• Manaslu Tsum Valley Trek. Both, in one trip, at 20 days.
