The Barbary Coast Trail is a marked trail that connects a series of historic sites and several local history museums in San Francisco, California. Approximately 180 bronze medallions and arrows embedded in the sidewalk mark the 3.8-mile (6.1 km) trail. The historic sites of the Barbary Coast Trail relate primarily to the period from the California Gold Rush of 1849 to the Earthquake and Fire of 1906, a period when San Francisco grew from a small village to an important shipping port.
