Besides being a popular excursion destination in Jammu, it is also a holy site, sharing the legend and sanctity of Lake Mansarovar. On the Eastern Bank of the Lake there is a shrine to Sheshnag, a mythological snake with six heads. The shrine comprises a big boulder on which are placed a number of iron chains perhaps representing the small serpents waiting on the tutelary deity of the Sheshnag. Two ancient temples of Umapati Mahadev & Narsimha as also a temple of Durga are situated in the vicinity of the Mansar lake. People take a holy dip in the water of the lake on festive occasions.

Newlyweds consider it auspicious to perform three circum-ambulations (Parikarma) around the lake to seek the blessings of Sheshnag, the lord of serpents, whose shrine is located on its eastern bank.

Certain communities of Hindus perform the Mundan ceremony (First hair cut) of their male children here.
