Upper Mustang is located between the rain shadow area of Annapurna and the Dhaulagiri mountains. This is one of the most secluded regions of Nepal extremely rich in tradition, culture, and its outstanding barren landscape. The entire region is still living back hundreds of years. To protect its raw nature and prominent lifestyle of locals, this region was closed until 1992 for foreign visitors. However, even after that, one needs to get several permits to trek to Upper Mustang. And, not only this, every year only a limited number of foreign visitors are allowed to traverse this region.
