Mustang Districtमुस्ताङ जिल्ला

Mustang is the valley of the upper Kali Gandaki, which cuts between Dhaulagiri (8,167 m) and Annapurna I (8,091 m) to form, by the measure of summit-to-river depth, the deepest gorge on Earth. Caught in the rain shadow of both massifs, the district receives under 260 mm of rain a year at Jomsom, its windswept headquarters and airstrip town; the landscape of the 3,573 km² district — Nepal's fifth largest, ranging from about 2,010 m to the 8,167 m summit of Dhaulagiri — is high desert of eroded cliffs, cave systems and irrigated oasis villages. The river bed yields the black shaligram fossils sacred to Hindus as forms of Vishnu.

Upper Mustang was the Kingdom of Lo, founded around 1380 by Ame Pal, whose square-walled capital Lo Manthang (about 3,800 m) preserves the king's palace and major 15th-century monasteries and has been on UNESCO's tentative World Heritage list since 2008; its rajas retained formal status until Nepal abolished the monarchy in 2008. Closed to foreigners until 1992 and still subject to a costly restricted-area permit, Upper Mustang remains one of the best-preserved enclaves of Tibetan culture anywhere, celebrated for the annual Tiji festival. Lower Mustang's Thak Khola is the homeland of the Thakali people, famed across Nepal as traders and restaurateurs, with apple orchards around Marpha among the country's best known.

Muktinath, at 3,710 m below the Thorong La, is one of the most important pilgrimage sites in the Himalaya — sacred to Hindus as a Divya Desam of Vishnu and to Buddhists, with 108 water spouts where pilgrims bathe. The 2021 census counted 14,452 people, making Mustang the second-least populous district, though one of only three Gandaki districts that grew over the decade (+0.69% a year); the sex ratio of 121.72 is Nepal's second-most male-skewed, tracking the seasonal tourism and trade workforce. The district lies within the Annapurna Conservation Area, and the new road up the Kali Gandaki toward the Korala border point with China is transforming the centuries-old salt-trade corridor.
