Formally known as BHAINSA LOTAN, it is a famous tourist spot where  a dam is built on the river Gandak (Gandak Project). This dam and its channels are the lifeline of north-western part of Bihar. This channel also irrigates some portions of eastern U.P. This dam is also generating hydro-electricity. This dam has been handed over to the nation by late Pandit Jawaharlal Nehru the then Prime Minister.  For any tourist interested in exploring natural beauty, a visit to the sylvan surroundings of Valmilki Nagar is a must, where the gushing streams of Gandak break the ascetic calm of the Himalayan foothills.

Bhainsalotan is also famous for Valmiki Ashram where Maharshi Valmiki, the author of the Ramayan is said to have passed some years. Lord Shiva temple, constructed by Bettiah Raj and  ancient Shiv-Parvati temple is also situated  here. VALMIKI NAGAR NATIONAL PARK AND TIGER RESERVE, spread across 544sq km, is a home for myriad wild animals and birds. Magnificent Himalayas provide a backdrop for this calm wild land.
