This region, also known as the Forbidden Kingdom was opened for tourists only in 1991 with limited numbers of people can visit in a year. This high desertic region is north of Jomsom, the headquater of this district. Jomsom is in the lower Mustang & the major part is the upper Mustang. The region is geographically and culturally part of Tibet and has a long rich and complex history, thus offering trekkers to explore the natural beautiful desertic landscape but also monasteries, castles and life styles unaffected by the outside modern world. It is very much different than the other trekking routes in the Himalayan Kingdom of Nepal. This area is quite expansive for trek because We have to apply for the special trekking permit through the government registered trekking company in immigration office & have to pay USD700.00 per person for ten days from Kagbeni to Kagbeni. In addition it require minimum of 2 people in a group.
