North of the Annapurnas the rain stops. Upper Mustang is Tibetan plateau in everything but name — ochre cliffs, cave dwellings cut into them a thousand years ago, and a walled capital at Lo Manthang that was a closed kingdom until 1992.
What the walking is like
High but not steep. Most of the route sits between 3,000 and 4,000 m, and the passes are short rather than punishing — the altitude never becomes the problem the Khumbu makes it. What you get instead is wind, which comes up the Kali Gandaki gorge every afternoon like clockwork, and sun with nothing in the air to soften it.
The landscape does the work here. This is not a mountain-viewpoint trek; it is a walk through eroded canyon country, past chortens and monasteries and villages of whitewashed mud brick, with Nilgiri and Dhaulagiri behind you rather than ahead.
The monsoon region
Mustang sits in the Annapurnas' rain shadow, which makes it the one trek in Nepal we actively recommend in June, July and August. While the rest of the country is under cloud and leeches, Mustang is dry, clear and — briefly — green along the irrigation channels. The Tiji festival in Lo Manthang, usually in May, is the other reason to time a trip precisely.
Permits and access
The restricted-area permit is US$ 500 per person for ten days and US$ 50 a day after that, and like Manaslu it needs two trekkers and a licensed guide. It is the most expensive permit in Nepal and it is non-negotiable — the fee is the price of the kingdom staying as intact as it has.
Access is a flight to Pokhara, a second short flight to Jomsom, and you walk from there. Jomsom flights go early because of the wind, so a cancelled morning is a whole lost day.
- Upper Mustang Restricted Area Permit — US$ 500 for 10 days, then US$ 50 per day
- Minimum two trekkers and a licensed guide
- ACAP (Annapurna Conservation Area) entry permit
Upper Mustang FAQs
Per person, for ten days, and it does not cover ACAP. It is the single biggest line on a Mustang quote and we show it separately rather than burying it in the trip price.
Yes — it is the whole point of the region. Expect the odd shower and note that the flights and the road in from Pokhara are still monsoon-affected even when Mustang itself is dry. We plan a buffer day for exactly that.
It is the least similar trek in Nepal to anything else in Nepal. If you have done teahouse trekking under big peaks and want something that is about culture and landscape instead, this is the one.
