Tapovan Hills are located 10km from the Deoghar Town. It is mainly famous for Tapo Nath Mahadev, the temple of Lord Shiva. It is named Tapovan because in the olden days it was a meditation spot (Tapobhumi) for the Nagas.
The site houses a beautiful temple dedicated to Lord Shiva and is popularly known as Taponath Mahadeva. Tourists can witness various caves on this hill, which served as a site for penance of Sri Sri Balananda Brahmachari and Sage Valmiki. One of the prime attractions of the site is the cave, which has a Shivalingam enshrined in it.
There is a cracked rock at Tapovan. In the inner surface of the crack, one can see a portrait of Hanuman. This is an amazing feat as it is practically impossible to insert a paint brush in the crack and draw anything. Below the hill there is a small cemented water body which is called Sukta Kunda (Sita Kunda) by the local people. It is a holy water body. It is said that Sita used to take bath here.
