Upper Mustang is an upper part of Mustang District, which is located in Nepal. The Upper Mustang was a restricted kingdom and demilitarized area until 1992 which makes it one of the most preserved regions in the world, with a majority of the population still speaking traditional Tibetic languages. Tibetan culture has been preserved by the relative isolation of the region from the outside world. Life in Mustang revolves around tourism, animal husbandry and trade.
