A nice place to go during winter time.We went to trekking to this place. We crossed Damodar river via a temporary wooden bridge. There are other routes that will take longer. After crossing the river nice village road starts. 4KM to the base of Mount BN(Biharinath). There is a temple. People were there doing mini-picnic. It took us roughly 2.25hours to reach to the top with enough snacks-adda breaks.After reaching a certain height we could get a view from the top. Once we reached at the top there was no view as everything was covered by trees. Total height is 1.3KM. The mid 500-1000 m is the difficult one. The last 300m is again easy.If not to the top people can go to 600-700m to get a view and sit there and then come back. We enjoyed the journey. The weather was also very good. The decent would be little more difficult. People can carry stick, that would help a lot (especially while coming down).
