To trek in Upper Mustang is a rare privilege. Here you will experience a way of life of true mountain people, who for hundreds of years, had very little contact with the rest of Nepal and retained their rich cultural heritage. Until recent times their king was officially recognized by the Government of Nepal. 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.
