Kolhua Hill can be reached from Hunterganj by crossing the Lilangen River or by trekking from the village. This hill is located at an altitude of 1,575 ft and gives a distinctive sky eye view known as Akash Lochan. It is also famous for the Kolhua Mela, which is held twice a year at the hill top.
Kolhua Mela is a religious fair, which is celebrated at the Kauleshwari Devi Temple. It is celebrated on the eve of Ram Navami and Magh Vasanth Panchami. For reaching this temple, tourists have to trek to the hill top, as the roads are very steep.
