Round Valley Regional Preserve

Round Valley Regional Preserve is a regional park just outside Antioch, CA and Brentwood, CA that is part of the East Bay Regional Parks (EBRPD) system. It is on Marsh Creek Road, approximately 5.2 miles (8.4 km) west of the intersection with Vasco Road. The park was begun in 1988, when Jim Murphy sold 700 acres (280 ha) of land to EBRPD. The land originally belonged to Mr. Davis' grandfather Thomas Murphy, an Irish immigrant, who had purchased the land in 1878 for a farming and ranching operation. The preserve has since expanded to encompass 1,911 acres (773 ha). The Round Valley parking area is one of the two staging areas and points of departure for tour buses that carry passengers into Vasco Caves Regional Preserve. Morgan Territory Regional Preserve adjoins Round Valley Regional Preserve on the Southwest. The park is near the edge of the Diablo Range, and its wooded hills are a sharp contrast with the almost treeless flat land of the Central Valley, which begins a few miles farther east.
