About this route
Upper Mustang is a narrow tongue of Nepali territory cut into the Tibetan plateau north of the Annapurna and Dhaulagiri massifs. Geopolitically it is Nepal; culturally and geographically it is Tibet. Here people speak Lo-ke (a Tibetan dialect), write in the Ume script, count by the Tibetan lunar calendar, and honour the twenty-fifth king of Lo, whose dynasty was not formally abolished but merely lost its status in 2008 along with the Nepali monarchy.
The Kingdom of Lo opened to foreigners in 1992. Before that, for political reasons — proximity to Tibet, the activity of Khampa guerrillas in the 1960s–70s, inter-state sensitivity — entry was forbidden. That is forty years of isolation following the Chinese Cultural Revolution, during which around 6,000 monasteries were destroyed in Tibet. In Mustang almost nothing was destroyed. Thubchen gompa (15th century), Jampa Lhakhang with its fifteen-metre statue of Maitreya, and the Chhoser cave complexes with 13th-century frescoes are surviving Tibetan Buddhism of the Sakya school in its unbroken form.
The route is fifteen days, seven of them on foot across the plateau at 3,000–3,850 metres. This is not a high-altitude trek — a maximum of 4,010 m at the Nyi La pass — but it is a dry, cold desert in the rain shadow of the Himalayas, where less precipitation falls than in the Sahara. The wind from midday is a steady 40–60 km/h. The landscape is red and ochre erosion walls, white stupas on waterless slopes, fields of buckwheat and barley around earthen villages. Nights are in local guesthouses: simple rooms, a gas stove, a shared shower, a generator for light until 22:00.
We don't promise “stepping outside the matrix” or a “reset of consciousness.” We offer fifteen days in one of the last surviving strongholds of pre-Chinese Tibetan culture — while it still survives. The road on the Chinese side was completed to the Mustang border in 2014; the jeep road from Jomsom to Lo Manthang in 2017. This window has no guaranteed length.

Safety and health
What you need to know before the route
Physical requirements
The route is rated difficulty 4 out of 10. There are no technical sections; the maximum altitude is 4010 m (one day, Nyi La pass), but the daily time on trail and the dry air make this far from a casual walk.
What you need to be able to do
Walk 5–7 hours per day with a day pack of 5–7 kg on a dusty dirt trail, with occasional rocky sections
Ascend 400–500 metres of elevation in a day (Gyula La, Nyi La passes) without technical equipment
Sleep at altitudes of 3000–3850 metres for six consecutive nights
Tolerate dry air at 15–25% humidity and winds of 40–60 km/h in the afternoon hours
On altitude sickness
At 3850 m, mild symptoms (headache, disturbed sleep, slight breathlessness on ascent) occur in a portion of any group. This is a smaller concern than on Kailash or EBC, but not an absent one. If you have no experience above 3000 m, add cardiovascular training in the three months before departure. Severe forms (HACE, HAPE) are rare at these altitudes, but not impossible.
On the dryness
The air in Mustang is drier than in most deserts in the world. Drink 3–4 litres of water per day. Nosebleeds in some participants are a normal reaction during the first 2–3 days and are not cause for alarm. Lips and hands crack — SPF cream and lip balm are essential.
Who the route is not suitable for
Pregnant women
People with uncontrolled hypertension, severe asthma, or chronic obstructive pulmonary disease
Those who tolerate poorly long jeep transfers on bumpy dirt roads
Age 65+ — an individual decision after consultation, not a prohibition. The route is technically more accessible than EBC and Kailash.
What we recommend doing in advance
Cardiovascular exercise 2–3 times a week (running, cycling, swimming) for 3 months before departure
A basic medical check-up (ECG, complete blood count) one month before departure
At least one trek at 2500–3500 m within the year before Mustang — advisable, but not mandatory
Equipment
Equipment for Mustang is lighter than for Kailash: a sleeping bag rated to −5 °C, not −15 °C. However, wind and dust protection are critical.
Essential
Trekking boots — broken in, mid-cut, with ankle support. The trail is predominantly dirt, but sections of scree and rocky slopes exist.
Sleeping bag rated to −5 °C comfort. Nights in Lo Manthang in March/April and October/November drop to −5 °C indoors; the gas stove runs only while the host keeps it lit.
Waterproof shell jacket and trousers (wind and moisture protection). Rain in Mustang is rare, but wind with dust is constant.
A light down jacket or warm fleece for evenings at camp.
Thermal base layer — one set; merino wool is preferable.
Gloves — fleece.
UV-protection sunglasses, category 3 — sun at 3800 m is intense even in winter.
SPF 50 cream for face and lips. The air is dry; skin cracks within 24 hours.
1.5 L water bottle + 0.5 L thermos.
Buff or scarf — dust and wind are constant; without face protection, coughing and mucous irritation set in by day three.
Personal first-aid kit — acetazolamide (on medical advice), ibuprofen, anti-diarrhoeal medication, oral rehydration salts, plasters, lip balm × 2, moisturising cream.
Important
Trekking poles (telescopic, two)
Headlamp + spare batteries (guesthouse electricity until 22:00 from generator)
Day pack 30–40 L + rain cover (serves as dust cover)
Thin trekking socks 3 pairs + warm socks 2 pairs
Wet wipes, toilet paper (shower in Lo Manthang is cold, or paid hot water at 200–500 NPR)
Asian power adapter
Optional
A book or downloaded playlist — evenings at guesthouses are long
A camera, if photography matters — Mustang's landscape in morning and evening light is unique
Power bank 10,000+ mAh (charging at lodges is often paid: 100–300 NPR per device)
A few small-denomination dollar bills for monastery donations
Altitude regime
The route climbs to 3850 m. Above 2500 m the body acclimatizes more slowly: pressure drops and there is 25–40% less oxygen. We schedule altitude gain to stay under 500 m per day above 3000 m and include acclimatization days.
Evacuation
The guide carries a link to Nepali rescue services and the insurance assistance line. The guide decides on evacuation at the first signs of acute mountain sickness (AMS) or injury. Each participant must hold insurance covering high-altitude evacuation up to 3850 m.
Before the trip
- Insurance covering high-altitude evacuation
- Medical clearance from a physician
- At least 4 weeks of cardio preparation
- Personal first-aid kit (we'll discuss the contents)

FAQ
Yes, this is the most logical next step in high-altitude experience. Maximum altitude 4010 m for one day, base sleeping altitude 3850 m, six nights above 3000 m — this is a controlled exposure. After Mustang, you can make an informed decision about EBC (5364 m) or Kailash (5630 m).
This is not a visa but a Restricted Area Permit, which the Government of Nepal has established as compensation for the cultural and ecological pressure on a restricted zone. The funds partially go to the Mustang Conservation Fund. This is a non-refundable government fee — even if the trip is cancelled, the agency refunds only its own portion of the cost. Factor this in when planning.
We arrange a jeep transfer Jomsom–Pokhara (12–14 hours) or wait in Jomsom at a guesthouse at our expense for the next available flight. What we do not cover is a missed international flight out of Kathmandu. Therefore, always leave 1–2 buffer days in Kathmandu between your return and your international departure, and take out travel insurance with trip interruption coverage.
Exact dates are determined by the Tibetan lunar calendar — usually late April or the first half of May; the ritual lasts 3 days. Carry-over Q-TR-UM-04 — we publish exact dates for the 2026 and 2027 seasons after confirmation with Chhoide Monastery, typically in January of the preceding year. The Tiji season is the busiest period in Lo Manthang; book 6 months in advance.
The minimum for a RAP is 2 people. Solo travel is technically possible at 2× the group price due to fixed costs for the permit, guide, and jeep. If you have a confirmed pair or a small group of 2–4 people, we organise a private itinerary.
Tibetan and Nepali cuisine is predominantly plant-based: dal bhat, vegetable momos, thukpa, tsampa, and buckwheat pancakes made locally (a Mustang speciality). A gluten-free diet is more difficult: tsampa (barley flour) and wheat noodles are dietary staples. Please state any dietary requirements at the time of booking. On the trekking section, choice is limited; menus are discussed with the guide in advance.
$300–500 in small-denomination dollar bills plus 30,000–40,000 NPR. There is an ATM in Lo Manthang, but it operates unreliably and cards are not accepted. Out-of-pocket expenses above Kathmandu run 30–50% higher — supplies are brought in by jeep, gas is expensive, electricity comes from a generator.
According to our statistics over the past four seasons, approximately 95% of participants complete the full route. Of the 5% who do not: half are weather-related flight cancellations at Jomsom with no possibility of recovering the transfer within the schedule; half are personal circumstances (injury, illness, urgent matters at home). We have had no cases of emergency evacuation from the route in the past four seasons.
