Located west of Sehawan Sharif, Manchar is said to be the largest natural lake in Asia, covering an area of 253 sq. km and maximum 5 meters deep. It is best visited in winter when the temperature is comparatively moderate and migratory birds flock to its vast expanse of water and marshlands. The fisher folk living here belong to the aboriginal Mohanna tribe (locally known as Mirbhars meaning Sealords) and are believed to be descendents of the Scythian Meds of Moenjodaro. They live as boat-people in their traditional high-powered wooden boats. The lake can be reached by road from Sehwan Sharif.
