Jomsom is a great place to start trekking. 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.
The highlight is a trek through the deepest gorge in the world carved by the Kali Gandaki River, which originates in the Tibetan plateau to eventually flow into the Ganges in India.
Not too far from Jomsom, you find 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 is a perfect place to find fossilized ammonites, known locally as Shaligram, which are found all along the upper reaches of the Kali Gandaki.
