Parshuram Mahadev Temple is a Shiva temple in Desuri tehsil in Pali district of Rajasthan state in India.  There are 500 stairs to reach down to the ancient cave. It is said that Parshuram, the sixth manifestation of Lord Vishnu, made the cave with his axe and used to worship the lord Shiva at this serene place in the foothills of the Aravalis mountain range. The cave, 3,995 feet above sea-level, has naturally made figures of Lord Ganesha and Lord Shiva and also has nine Kunds which never go dry.
