The Upper Mustang comprise the northern two-thirds of Mustang District of Dhawalagiri Zone, Nepal. The southern third of the district is called Thak and is the homeland of the Thakali, who speak the Thakali language, and whose culture combines Tibetan and Nepalese elements. Life in Mustang revolves around tourism, animal husbandry and trade. This isolation helped the people of Mustang to maintain their lifestyle and heritage that remained almost unchanged for centuries. Hidden behind the majestic Himalayan ranges of Dhaulagiri and Annapurna, Mustang is filled with beautiful trekking zones.
Long closed to foreigners because of its strategic location on the Tibetan border, Mustang has only been open to trekkers for less than a decade and is closely regulated by the Nepali government. Only organized treks are allowed into the region, and those require an expensive trekking permit. Consequently, treks into Mustang are among the most expensive in Nepal. The brown landscape, jagged peaks, and mud-walled villages are reminders of what Tibet must have been like before the Chinese invasion.
