Tsum Valley

Autumn (late September to November) and spring (March to May) are the two reliable seasons for the Tsum Valley Trek. Autumn brings the clearest skies after the monsoon finishes and is the most popular period; temperatures are moderate at lower altitudes and cold but manageable at Mu Gompa. Spring is warmer in the Budhi Gandaki gorge, rhododendrons are in flower below 3,000 m, and the valley trails are dry.

Winter (December to February) is cold and the upper valley can receive snow above 3,000 m, but the trek is still possible for well-equipped parties because there is no high pass to cross. The summer monsoon (June to August) brings rain, leeches and some landslide risk on the lower trail, though the inner Tsum Valley sits in a rain shadow and is drier than the main Budhi Gandaki gorge. The season cards above give the month-by-month picture.

The Tsum Valley is a restricted area, so trekkers must hold a Tsum Valley Restricted Area Permit (RAP), arranged through a registered Nepali agency, and the trek requires a minimum group of two with a licensed guide. The Tsum Valley RAP costs approximately USD 35 per week in the September to November high season and around USD 20 per week the rest of the year; current rates are confirmed at the time of booking.

In addition, all trekkers need the Manaslu Conservation Area Permit (MCAP) at NPR 3,000 for non-SAARC nationals and a Trekkers' Information Management System (TIMS) card. No Annapurna Conservation Area Permit is required because the Tsum Valley trek is an out-and-back that does not cross into the Annapurna drainage. Swotah arranges all three permits once you provide a passport copy and photos, and confirms fees before departure.

Accommodation in the Tsum Valley is teahouse-style, simpler than on the main commercial circuits because the region is restricted and lightly visited. Lower stops at Arughat, Soti Khola and Macha Khola have basic guesthouses, while Chumling and Chokhangparo have small lodges with shared facilities and a reasonable menu. Above Nile, the options thin out and the upper valley around Mu Gompa offers very simple rooms, often attached to the monastery.

The upper Tsum Valley follows a vegetarian, animal-friendly culture, so expect simple food and modest surroundings high up. A three-season or four-season sleeping bag is important from Nile upward, where nights fall below freezing at altitude. Kathmandu offers comfortable hotels at the start and end of the trek.

Food on the Tsum Valley Trek is teahouse cooking, and dal bhat (lentil soup, rice and vegetable curry) is the staple at the teahouses across the lower and middle valley because lodges typically refill it for free. The menu in upper Tsum reflects the valley's Buddhist non-violence tradition: meat is largely absent, and the food is vegetarian, with Tibetan bread, noodles, potatoes and tsampa alongside the dal bhat.

Swotah includes three meals a day on the trek. For water, aim for 3 to 4 litres a day to support acclimatisation, and treat it rather than drinking untreated stream water: boiled water is sold at lodges, and purification tablets, a filter or a UV pen all work. Carry a reusable bottle rather than buying plastic, and be aware that water sources are limited in the high upper valley.

The Tsum Valley Trek starts with a jeep drive of 7 to 8 hours from Kathmandu to Arughat (600 m), the road head on the Budhi Gandaki. The road is rough in places, and the drive can be longer during monsoon season. The trek begins from Arughat and follows the Budhi Gandaki north before branching into the Tsum Valley via Philim.

The trek is out-and-back, returning to Arughat the same way it started, then driving back to Kathmandu. There is no exit over a pass to a different road head. Swotah runs the road legs by private jeep, which handles the rough sections better than a shared bus, and the schedule includes realistic drive times rather than optimistic estimates.

Mu Gompa, also written Mu Gumba, sits at 3,700 m at the head of the Tsum Valley and is the largest monastery in the region. It belongs to the Nyingma school of Tibetan Buddhism, houses monks and nuns from across the valley, and holds a significant collection of thankas and religious texts. The climb from Nile on day 10 takes about 3 hours; the itinerary builds in a full extra day (day 11) at Mu Gompa for monastery exploration.

Lower in the valley, Rachen Gompa is a nunnery at roughly 3,240 m whose enclosure is, by tradition, entered only by women. Rinchenling Gompa in Halji is another important site. Walking clockwise around all mani walls and chortens, removing footwear before entering temples, and following the guide's directions inside the gompas are the basic expectations. Tsum is a beyul, a hidden valley blessed by Padmasambhava, and the communities treat it accordingly.

A licensed guide is mandatory on the Tsum Valley Trek: Nepal's permit rules for restricted areas require a guided group of at least two trekkers, booked through a registered agency. Swotah's guides hold Ministry of Tourism licences, have Nepal Mountaineering Association first-aid training, and know the Tsum Valley route and its monasteries.

A porter is strongly recommended on this long, remote trek. One porter carries 20 to 25 kg, and Swotah caps loads at 25 kg because porters work at the same altitude as trekkers. Swotah provides a free duffel bag for the porter, so you walk with a light daypack carrying warm layers, water and a first-aid kit, while the heavy bag travels ahead.

Mobile coverage in the Tsum Valley is limited. Nepal Telecom (NTC) gives the best signal in the lower valley and around Chumling; above Chokhangparo there are long dead zones, and the upper valley around Mu Gompa is essentially off-grid. Swotah provides a tourist SIM so trekkers have a contact point in the areas where a signal exists.

Wi-Fi is available at some guesthouses in the lower valley for a fee, but is absent from the upper valley. Charging sockets are available at lodges further down but cost a small fee per device, rising with altitude. A power bank or small solar charger is important for the upper section, where cold nights drain batteries quickly, and the trek above Nile should be treated as off-grid for planning purposes.

Responsible trekking matters in the Tsum Valley, where the restricted status, small communities and strong Buddhist tradition make the valley more fragile than a standard commercial route. Carry a reusable bottle and treat your own water, pack out all waste, respect the vegetarian culture in the upper valley, ask before photographing people or gompa interiors, and walk clockwise around mani walls and chortens.

Tipping is customary though not mandatory: a common guideline is 10 to 15% of the trip cost, shared among the guide, porter and driver. Tips go directly to the seasonal workforce in a remote region with little other income. Booking with a registered operator like Swotah ensures the restricted-area permits, staff insurance and fair porter loads are managed correctly, which matters especially in a protected area like Tsum.
