To trek in Upper Mustang is a rare privilege. Here you will experience the way of life of true mountain people, who were not much in touch with the rest of Nepal for hundreds of years, and even until recent times had an officially recognized king.
In many ways, a trek into Upper Mustang is similar to trekking in Tibet, as geographically it is a part of the Tibetan plateau. The district of Mustang was, until 1950, a separate kingdom within the boundaries of Nepal. The last king, the Raja of Mustang, still has his home in the ancient capital known as Lo Manthang.
Upper Mustang was opened to non-Nepali trekkers only some fifteen years ago and even today, access is still highly restricted. To enter Upper Mustang, that is to travel further north from Kagbeni, trekkers need special trekking permit and must be accompanied by a government appointed officer.
