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.
