Kolhua Hill, 1,575 ft high, lies about 10 km south-east of Hunterganj in
Chatra District. Akash Lochan (Sky Eye), the top of the hill, provides an excellent view of the surroundings.
A number of ancient temples can be found, prominent being
Kauleshwari Devi Temple, which is dedicated to Goddess Kali.
Kolhua is accessible from Hunterganj, and one has to cross the Lilangen River, which has been bridged.
