About 62 km from Jammu, Mansar is a beautiful lake sounded by forest-covered hills with its length more than a mile and width half-a-mile. Besides being a popular excursion destination in Jammu, it also has provision for boating for which adequate facilities are provided by the J&K Tourism. The history of mansar and surinsar goes back to the time of Mahabhartata. Babar Vahan, son of Arjun and Ulpi (daughter of king Nag), was ruling this area during Mahabhartata. After the war of the mahabhartata arjun performed "Ashwamegh Yagya" to prove his supriority over the land. The horse (used as sign of power for Ashwamegh Yagya) was captured by Babar Vahan at village 'khoon' nearby village Ramkot on dhar Udhampur road where Arjun was killed by babar vahan. With joy of victory, babar vahan presented the head of Arjun to his mother Ulpi. She told him that he has killed his father. To make arjun alive again, mani from sheshnag was required. Hence babar vahan made a surang through his arrow and formed surangsar which is now named as surinsar. After defeating sheshnag and capturing mani, babar vahan came out at manisar later on known as mansar.
