Upper Mustang Trek 2026: Trekking the Last Forbidden Kingdom
What is Upper Mustang? Upper Mustang is the former Kingdom of Lo — a arid, Tibetan-style trans-Himalayan region behind the Annapurnas, with the walled capital Lo Manthang. It stayed closed to outsiders until 1992 and remains a restricted area, which keeps visitor numbers tiny and the culture intact. Here’s the 2026 guide.
Permits and cost (2026)
- Restricted-area permit: USD 500 for the first 10 days, then USD 50/day thereafter — one of Nepal’s most expensive permits, reflecting its protected status.
- Guide + group of 2 minimum: mandatory, as with all restricted areas.
Route
Most fly to Jomsom, then trek north through Kagbeni, Chele, Ghami, and Charang to Lo Manthang (3,840 m), with optional day trips to the caves of Chhoser. Plans run 10-14 days.
| Plan | Days | Max altitude |
|---|---|---|
| Jomsom-Lo Manthang return | 10-12 | ~4,000 m |
| + Muktinath extension | +3 | 3,800 m |
What makes it unique
- Red-walled cliffs, cave dwellings, and centuries-old Buddhist gompas.
- The Tiji Festival (typically May/June) reenacts a demon-subduing myth with masked dances.
- A high-desert landscape unlike anywhere else in Nepal.

FAQ
Why is it so expensive?
The USD 500/10-day permit funds conservation and limits footfall to protect the fragile culture and water supply.
Best season?
May-June (for Tiji) and Sept-Oct. Avoid the peak winter when temperatures plunge and lodges close.
Can I go independently?
No — restricted area requires a licensed guide and minimum two trekkers.

The restricted-area permit
Upper Mustang requires a Restricted Area Permit (RAP) costing $500 per person for the first 10 days, plus $50 per extra day. You must trek with a licensed guide and at least one other trekker (no solo trekking). Permits are arranged through registered Nepali agencies.
Trek highlights
- Lo Manthang: The walled capital of the former Kingdom of Lo, with a 15th-century monastery, royal palace, and Tibetan Buddhist culture.
- Sky caves: Thousands of man-made caves carved into cliffs above the Kali Gandaki, some dating back 3,000 years.
- Tiji Festival: A 3-day Tibetan Buddhist festival in Lo Manthang (usually May) featuring masked dances and rituals.
- Kali Gandaki gorge: The world’s deepest gorge, between Dhaulagiri (8,167 m) and Annapurna (8,091 m).
Best time
May–October. Upper Mustang lies in the rain shadow, so it’s one of the few Nepal treks possible during monsoon (June–August). Winter (November–March) is extremely cold and many guesthouses close.
Frequently asked questions
How fit do I need to be? Moderate fitness. The trek reaches 4,200 m but involves gradual ascents on jeep tracks and trails. No technical climbing.
Can I drive instead of trek? Yes — a rough jeep road now reaches Lo Manthang. 4WD tours take 5–7 days round-trip from Pokhara.
