Manaslu Circuit Trek

The Manaslu Circuit is rated Challenging and earns that rating in two specific places: the sustained high-altitude walking across multiple days above 3,500m, and the Larkya La crossing itself. Daily walking time runs 5-7 hours on most days, with the pass crossing day requiring 9-10 hours from a 3-4am start.

The terrain varies considerably. The lower gorge (Soti Khola to Deng) involves rocky riverside trail with frequent bridge crossings and is not technically difficult but is unrelentingly steep in sections. The middle section (Deng to Namrung) adds altitude to the physical load. Above Namrung, the trail is on open high-altitude terrain with loose rock and potential for snow.

The Larkya La approach from Dharmasala involves steep rocky and often icy slopes at and above 5,000m. Trekking poles and traction aids (microspikes or crampons in season) are strongly advised. Physical fitness needs to be higher than for ABC or the Poon Hill circuit. Specifically, cardiovascular capacity at altitude matters more than pure leg strength because the cumulative days of walking at 3,500-4,500m deplete reserves that low-altitude training cannot fully replicate. Previous multi-day high-altitude trekking experience is genuinely recommended.

Begin cardiovascular training 10-12 weeks before departure for the Manaslu Circuit. The circuit accumulates more total altitude gain than ABC and requires sustained output over 12-14 consecutive days. Running, cycling, and hiking with a loaded pack are all relevant. The goal is being able to walk 6-7 hours daily without the last two hours becoming a survival exercise.

High-altitude experience from a previous trek helps calibrate your acclimatisation response. If this is your first time above 4,000m, consider whether a shorter introduction at altitude before Manaslu would be wise. Even a week at the ABC or Langtang level teaches you how your body handles thin air. For Manaslu specifically, the acclimatisation rest day at Samagaun (3,520m) and the short day to Samdo (3,860m) are built into the itinerary for good reason; our guides will not shorten them.

Carry acetazolamide (Diamox) prescribed by your doctor. Diamox does not prevent altitude sickness but it supports acclimatisation when used correctly. Know the AMS symptoms cold. On a restricted-area trek with no quick road access, early recognition and descent are more important than on accessible routes. Travel insurance that explicitly covers emergency helicopter evacuation from a restricted area is not optional.

Four permits are necessary for this trek. The most significant is the Manaslu Restricted Area Permit (RAP), which costs USD 100 per week (Sep-Nov) or USD 70 per week (Dec-Aug), with additional fees of USD 15/day beyond the first week (Sep-Nov) and USD 10/day (Dec-Aug). The RAP is mandatory for the restricted zone from Jagat to Samagaun and for the pass, and it must be obtained through a registered trekking agency. It cannot be obtained by individuals.

The Manaslu Conservation Area Permit (MCAP) is also required for all foreign nationals entering the Manaslu Conservation Area, costing USD 27 per person.

Additionally, the Annapurna Conservation Area Permit (ACAP) is required because the circuit exits through Dharapani and Besi Shahar, costing USD 27 per person as well.

We also need a TIMS Card (Trekkers' Information Management System), which costs NPR 2,000 per person (approximately USD 15), required when passing through the Annapurna Conservation Area section of the route.

Finally, a Chumnubri Rural Municipality Permit is needed as well, costing USD 100 per week (Sep-Nov) or USD 75 per week (Dec-Aug). This permit is required for the core Manaslu Circuit area, covering wards 1-4 of Chumnubri Rural Municipality, and is obtainable through a licensed agency.

The Manaslu Circuit spends more time above 3,500m than most other popular treks in Nepal, which is its key altitude risk factor. The sleeping altitude sequence is: Namrung 2,630m, Lho 3,180m, Samagaun 3,520m, Samdo 3,860m, Dharmasala 4,460m. The jump from Samdo to Dharmasala (600m gain in a short day) followed by the pass crossing to Bimthang (5,106m summit, 3,590m sleep) is the most extreme segment.

Our guides carry a pulse oximeter on every Manaslu trek and check readings at Samagaun, Samdo, and Dharmasala. A resting SpO2 below 78% at Samagaun or below 72% at Dharmasala, combined with symptoms, warrants descending rather than continuing. The mandatory acclimatisation day at Samagaun and the short day to Samdo are the insurance against rushing this segment.

High-altitude exposure on the pass crossing day is the greatest individual AMS risk: spending several hours above 5,000m in cold, often windy conditions while physically exerting. Anyone who shows HACE symptoms (confusion, inability to walk straight) or HAPE symptoms (shortness of breath at rest, persistent cough) on the pass must descend immediately regardless of how close the far side is. Helicopter evacuation from the Manaslu region is possible but requires clear weather and a landing zone. Bimthang and Samagaun are the main options.

The teahouse standard on the Manaslu Circuit is lower than the Annapurna routes, which is part of what makes it feel genuinely remote. In the lower gorge (Soti Khola to Deng), guesthouses are basic but functional. From Namrung upward, the rooms are typically wooden boards, thin mattresses, and communal toilets. Above Samdo, Dharmasala is the most basic stop, a handful of teahouses with very limited menu options and cold conditions even in October.

Food quality on the circuit is honest rather than elaborate. Dal bhat is reliable and filling everywhere. Noodle soup, potato dishes, and eggs round out most menus in the higher villages. Some teahouses in Samagaun offer Tibetan bread and butter tea, worth trying even if you adjust the seasoning. Alcohol is available but our team advises against it above 3,000m. Carry electrolyte tablets and high-calorie trail snacks. The calorie deficit across 12 days at altitude is real and teahouse portions are not always large enough to compensate.
