Derawar Fort, about a hundred kilometres east of Khanpur in the heart of the Cholistan Desert, is the largest and most impressive of the Cholistan forts. The square mud-brick fortress with its forty massive bastions stands forty metres high above the desert floor and is visible across the open plain from a remarkable distance. The walls are about 1.5 kilometres in circumference.
The fort is in private ownership of the Abbasi family — the descendants of the Bahawalpur Nawabs — and entry to the interior requires their permission. The exterior is freely visited, and the white royal cemetery with its onion-domed pavilions at the base of the walls is one of the most photogenic sights in southern Punjab. Best visited as part of a day trip from Bahawalpur or as an overnight desert camping trip.
