Upper Mustang Trek — 15 Days

Upper Mustang — the Forbidden Kingdom — is Nepal's most dramatic restricted-area trek: a 15-day journey into a high-altitude Tibetan plateau that was closed to all outsiders until 1992. The landscape is unlike anywhere else in the Himalaya: eroded badlands of ochre, crimson, and grey carved by wind over millennia, cave monasteries cut into cliff faces, whitewashed chortens marking village boundaries, and the walled medieval capital of Lo Manthang rising from the desert at 3,840 m.

The route enters through Jomsom (by mountain flight from Pokhara) and follows the ancient salt-trade corridor up the Kali Gandaki gorge — the world's deepest valley, sliced between Dhaulagiri (8,167 m) and Annapurna I (8,091 m) — northward through Kagbeni, Chele, Syangboche, and Ghami to Lo Manthang. Two days are spent in Lo Manthang exploring the royal palace, the four-storey Thubchen Gompa with its remarkable Thangka collection, and the cave monastery of Chhoser, before the return south via the high plateau route past Dhakmar's red-cliff villages.

Upper Mustang receives so little rainfall (300 mm/year) that it is the only region in Nepal open for trekking year-round — even during the summer monsoon. The high-desert plateau makes it the one trekking destination where July and August are genuinely viable.

The USD 500 Permit: Is It Worth It?

Upper Mustang requires a USD 500 restricted area permit (10 days; USD 50/extra day). This is deliberate government policy — limiting visitor numbers to protect one of the most fragile cultural and ecological landscapes in Asia. For the trekker, it means sharing the trail with perhaps 30 other foreign visitors over 15 days. The Lo-ba people of Lo Manthang still speak Tibetan, dress in traditional chuba, and practise a form of Tibetan Buddhism little altered since the 15th century. That experience has a price, and USD 500 is it.

Best season: Year-round (unique rain-shadow area). Access: Pokhara–Jomsom mountain flight + jeep. Permit: USD 500 restricted area permit (arranged by us).
