It lies in the South Delhi Ridge of Aravalli mountain range in Faridabad tehsil of Faridabad district in the Indian state of Haryana. It is to the immediate south of India's national capital Delhi, within the NCR.

It is also the first ever site discovered in the Aravalli range containing cave paintings, which date back to 20,000-40,000 BP. This makes it the oldest human habitation discovered in Haryana and Delhi NCR.
