Halesi Mahadev is one of the most important Shiva shrines in the country. Hindus, Buddhists and the Kirats go regularly to this pilgrimage site. The temple is located in a cave that dates back to the 12th century. While the Hindus believe it to be a Shiva shrine, Buddhist believe that it is associated with the legend of Padmasambhava and a place where Vajrayana Buddhism was practised. The Kirats have their own history of the cave that lies between the Sunkoshi and Dudhkoshi rivers.
