Jomsom lies to the north of Pokhara in Mustang district, and is the main gateway to Upper Mustang. It lies to south of the village of Kagbeni, a Tibetan influenced village filled with prayer wheels, chortens and a Buddhist monastery. The trail passing through Jomsom follows the Kali Gandaki River which forms the deepest ravine in the world; on one side lies the Annapurna mountain range and on the other side is Dhaulagiri. The river freezes during winter and flows with rainwater and melting snow in summer and monsoon.
