Pavagadh Hill is situated within a plain in Panchmahal district, Gujarat, western India. At its base is the historical city of Champaner, while the hill station of Pavagadh was built upon the volcanic cone itself. A volcanic eruption occurred here approximately 500 million years ago and the etymology of its name is associated with eruption: Pavgadh means "one fourth hill" or "fire-hill", though a legend surrounding its formation is that the right foot of Sati is believed to have fallen at Pavagadh and God "sent a large hill as per the request of Rishi Vishwamitra to fill up a deep valley so that the sage's cows do not fall into it." With Champaner, Pavagadh hill forms the Champaner-Pavagadh Archaeological Park, which is spread over an area of more than 1329ha. The site is 50km east of Vadodara and 42miles south of Godhra.
