About 6 km to the north of Bharatpur, on the way to the Chitwan National Park, is a prominent pilgrimage site Devghat, at the confluence of the Trishuli and the Kali Gandaki rivers, which then form the Narayani, a major tributary of the Ganga. Confluences of major rivers such as these are considered very holy. On the day of Makar Sankranti, the first day of the Nepali month of Magh in January, pilgrims converge here to take holy dips. There are a large number of shrines, temples, ashrams and old age homes at Devghat. Balmiki Ashram was a retreat used by the great Hindu sage Balmiki, where Sita came to live with her two sons Lav and Kush after separating from Ram. The ashram is situated in a forest on the bank of the Tribeni River, at the southwestern corner of the national park.
