Upper Mustang lies in the Mustang district of Gandaki province of Nepal and is adjacent to the Tibetan Autonomous Region of China in the north. Its history can be traced to the 14th century, founded by the warrior Ame Pal. Formerly known as the Kingdom of Lo, Upper Mustang was a restricted area and opened to westerners in 1992 only, and still, the region is heavily restricted. The restriction was imposed because, in the 1950s, Tibet’s Khampa guerillas fought back from a stronghold in Upper Mustang. Even today, it hasn’t changed much due to its remoteness. Tibetan culture is still alive in that area. For this reason, it is known as the Forbidden Kingdom. A special permit from the Government of Nepal is still required to visit Upper Mustang.
