Mount Diablo is a mountain in Contra Costa County, California in the San Francisco Bay Area, located south of Clayton and northeast of Danville. It is an isolated upthrust peak of 3,864 feet (1,178 m), visible from most of the San Francisco Bay Area and much of northern California. Mount Diablo appears from many angles to be a double pyramid and includes many subsidiary peaks, the largest and closest of which is the other half of the double pyramid, North Peak, nearly as high in elevation at 3,557 feet (1,084 m) and about one mile northeast of the main summit.
