Pilgrims in large number visit the shrine on the full moon night of Sawan to participate in the festival to worship Lord Shiva.

A few kilometers further ahead of Sudh Mahadev is Mantalai. It is surrounded by lush deodar forests. It is believed that it’s the same place where lord Shiva got married to goddess Parvati. Besides the Shiv temple, you can also visit the complex created by Swami Dhirendra Brhamchari which includes a tree shaped house. An excursion through the woods to Naina Devi is 5 Kms from Mantalai. It provides excellent views of the mountain landscape all round.
