Asola-Bhati Wildlife Sanctuary covering 32.71 km2 area on the Southern Delhi Ridge of Aravalli hill range on Delhi-Haryana border lies in Southern Delhi as well as northern parts of Faridabad and Gurugram districts of Haryana state. Biodiversity significance of Ridge lies in its merger with Indo-Gangetic plains, as it is the part of the Northern Aravalli leopard wildlife corridor, an important wildlife corridor which starts from the Sariska National Park in Rajasthan, passes through Nuh, Faridabad and Gurugram districts of Haryana and ends at Delhi Ridge. This protected area contains one of the last surviving remnants of Delhi Ridge hill range and its semi-arid forest habitat and its dependent wildlife. Once the whole Delhi Ridge was a forested area, but development has destroyed several parts of it. Historical place around sanctuary are Surajkund and Anangpur Dam (both in Haryana), Tughlaqabad Fort and Adilabad ruins (both in Delhi), Chhatarpur Temple (in Delhi). There are several dozen lakes formed in the abandoned open pit mines in and around the sanctuary. It is contiguous to the seasonal waterfalls in Pali-Dhuaj-Kot villages of Faridabad and the sacred Mangar Bani. From Wikipedia
