Nilsagar
A large ancient tank west of Nilphamari town, linked in legend to King Birat and visited by winter birds.
Nilsagar is a broad, square tank of about 21 hectares in Gorgram union, north-west of Nilphamari town. It was long known as Birat Dighi, and local legend links it to King Birat of the Mahabharata, said to have dug it for his cattle. The name Nilsagar, "blue sea", was given after independence.
Today the tank is surrounded by tall trees and a raised walkway, with a temple on its bank and quiet ghats. In winter, migratory ducks rest on the water, and the place becomes a favourite picnic and walking spot for people from Nilphamari and Saidpur. Early mornings, when mist sits on the water and the birds are active, are the most atmospheric time to visit.
