Upper Mustang, once the forbidden kingdom of Lo, is one of the last places on earth where ancient Tibetan culture remains virtually intact. Nestled in the rain shadow of the Annapurna and Dhaulagiri ranges, this surreal landscape of eroded canyons, ochre cliffs, and wind-sculpted terrain feels like stepping onto another planet. The trek takes you through walled medieval villages and to the walled city of Lo Manthang, the capital of the ancient Lo Kingdom. Ancient cave dwellings, sky-burial sites, and centuries-old monasteries make this one of the most culturally rich and visually striking destinations in all of Nepal.
