The Cholistan Desert sprawls south and east of Khanpur, the Pakistani extension of the Thar Desert that runs into India. It is Pakistan's largest desert and one of its emptiest landscapes — pale sand dunes, salt pans, scattered acacia, and the long line of ruined Bahawalpur forts that marked the wells of the medieval caravan routes.
The desert is at its most accessible in the cool months from November to February. Annual events worth timing a trip around include the February Cholistan Desert Jeep Rally — a 500-kilometre off-road race that brings drivers from across South Asia — and the camel-herding semi-nomadic Rohi people who still live in the central desert. Tours are available from Bahawalpur and Rahim Yar Khan; independent travel requires a 4WD and ideally a local guide.
