Marin County in the Bay Area of California is a bedroom community across the Golden Gate Bridge to the north of San Francisco, affluent Marin County is home to ex-hippies and dot-com millionaires. It has rugged wilderness areas on its western coast, while towns on the Bay have a nautical air dating to the 1800s.
Most of the county's population resides on the eastern side, with a string of communities running along San Francisco Bay, from Sausalito to Tiburon to Corte Madera to San Rafael. The interior contains large areas of agricultural and open space; West Marin, through which State Route 1 runs alongside the California coast, contains many small unincorporated communities whose economies depend on agriculture and tourism.
Notable features of the shoreline along the San Francisco Bay include the Sausalito shoreline, Richardson Bay, the Tiburon Peninsula including Ring Mountain and Triangle Marsh at Corte Madera. Further north lies San Quentin State Prison along the San Rafael shoreline.
