Round Top is an extinct volcano in the Berkeley Hills, just east of Oakland, California. The peak lies entirely within the bounds of Contra Costa County. In 1936, the area surrounding the peak was established as Round Top Regional Park, one of the first three parks of the East Bay Regional Parks District. The park was renamed Sibley Volcanic Regional Preserve for the second president of the park district (1948 to 1958), Robert Sibley, shortly after his death in 1958.
