National Chambal Sanctuary, also called the National Chambal Gharial Wildlife Sanctuary, is a 5400km2 tri-state protected area in northern India for the protection of the Critically Endangered gharial, the red-crowned roof turtle and the Endangered Ganges river dolphin. Located on the Chambal River near the tripoint of Rajasthan, Madhya Pradesh and Uttar Pradesh, it was first declared in Madhya Pradesh in 1978, and now constitutes a long narrow eco-reserve co-administered by the three states. Within the sanctuary, the pristine Chambal River cuts through mazes of ravines and hills with many sandy beaches. It is part of the Kathiawar-Gir dry deciduous forests.
