The Barbary Coast Trail connects twenty of San Francisco's most important historic sites. From the Old Mint downtown to the oldest Asian temple in North America to the historic ships at Hyde Street Pier, walkers follow bronze medallions embedded in the sidewalk and discover decades of earthshaking history. Guided tours can be arranged by appointment. Printed guides for self-guided tours are available at several San Francisco bookstores. There are audio walking tours available as well - https://barbarycoasttrail.org/tours/ .
