Upper Mustang

Sheltered by some of the tallest mountains of the world and the Tibetian plateau, Mustang District of Nepal is also famous for being the last Forbidden kingdom where its ancient cultural capital Lo Manthang is the only remaining walled city of Nepal. Up until 1992 visitors were not allowed in Mustang region and even today tourism in Upper Mustang area is strictly regulated requiring any foreigner to have 10 days permit for $500 USD and $50 extra per additional day which can be considered the most costly permit in Nepal though every penny spent is worth the experience gathered in the region.
