Dunagiri is about 50 kms. from Nainital and 15 kms. from Dwarahat. It is situated on an altitude of 8000 feet. Dunagiri Devi temple is quite popular in Kumao Himalayas and is considered as one of the powerful Shakti pithas. 
The temple is located on a small hillock and there are about 500 steps to reach the temple. The stairway has a well protected roof and has huge bells all along its way up to temple. 
About few meters below the main temple, there is a small shrine for Hanuman and little below that is a shrine for Bhairav. 

As per the legend, Pandavas took shelter in Dunagiri and Guru Dronacharya is also believed to have done Tapasya here. 
It is said that Mahavatar Babaji had done Tapasya here, and even to this day the tree is preserved and a platform is built with a small sign board mentioning Babaji’s place of Tapasya. 
It is a wonderful and peaceful place and is worth visiting.
