Jomsom, also known as Dzongsar (New Fort) in Mustang district situated at an altitude of about 2,700 meters (8,900 ft) in western Nepal.

 Jomsom is the starting point of the scenic trekking routes in Upper Mustang and Manang. The diverse landscape and culture found along this trekking route give marvelous insight into the way of life of Nepali people of various ethnic groups. Not too far from Jomsom is Muktinath, the famous pilgrimage site for Buddhists as well as Hindus. To Hindus, Muktinath is a sacred place of salvation. They believe that bathing in the waters here guarantees salvation after death. The Hindu god, Brahma, is said to have lit the eternal flames that burn at Muktinath. To Buddhists, Muktinath is a place where the great sage Guru Rinpoche (Padmasambhava) who brought Buddhism to Tibet, came to meditate. The area around Jomsom is a perfect place to find fossilized ammonites, known locally as Shaligram, which are found all along the upper reaches of the Kali Gandaki.
