Mustang
Mustang is Nepal's forbidden kingdom — a high-altitude desert of red rock canyons, wind-carved cliffs and ancient cave dwellings, culturally and geographically part of Tibet. Upper Mustang requires a restricted-area permit and remains one of the most distinctive regions in the Himalaya.
Nowhere else in Nepal looks like Mustang. Rain shadow keeps it dry when the rest of the country is monsoon-wet, making it ideal for summer trekking. Lo Manthang, the walled capital, preserves Tibetan Buddhist culture, royal palaces and cliff-side monasteries few travelers ever see.
Best time to visit: June to September is the classic Mustang window — dry when the rest of Nepal is in monsoon. May and October are also good but colder at night.
Getting there: Fly to Jomsom from Pokhara (weather permitting), then jeep or trek north. Overland from Pokhara via Beni is possible in the dry season.
Recommended stay: 7–14 days for Upper Mustang; 2–3 days for lower Mustang (Muktinath/Jomsom).
Upper Mustang requires a restricted-area permit arranged through a registered agency.
Carry warm layers — nights are cold even in summer.
Fuel and supplies are limited; travel with a group or organized trek.
