Bolinas (alternates: Ballenas, Baulenas, Baulings, and Bawlines) formerly Juggville is a coastal unincorporated community in Marin County, California in the San Francisco Bay Area. Bolinas is located 10 miles (16 km) west-southwest of San Rafael, at an elevation of 36 feet (11 m). The population of the Bolinas CDP (Census-designated place) was 1,620 at the 2010 census.
The community is perhaps best known for its reclusive residents. Historically, it is only accessible via unmarked roads; any road sign along nearby State Route 1 that points the way into town has been torn down by residents. Bolinas and its reclusive reputation are featured in the 1981 novel Ecotopia Emerging by Ernest Callenbach. It was also the mythical setting for Richard Brautigan's novel In Watermelon Sugar.
Bolinas is located on the California coast just off of State Route 1 approximately 30 miles (50 km) north of San Francisco.
