Castle Hill

Castle Hill lies along the rolling inland valleys of Contra Costa County, where the East Bay rises toward Mount Diablo. This residential area stands east of San Francisco Bay, among low ridges and open land shaped by the transition from the Bay’s urban core to its inland foothills. Mount Diablo State Park protects extensive terrain on the mountain nearby and is a major regional destination for walking and cycling. Contra Costa County was created in 1850; its Spanish name, meaning “opposite coast,” refers to its position across the Bay from San Francisco.
