Surf pounding the rocky Pacific Coast shoreline north of the Point Bonita Lighthouse makes it clear why a lighthouse was necessary at the mouth of San Francisco Bay. The Point Bonita Light was first lit in 1855; it still is an active lighthouse, operated by the U.S. Coast Guard yet stationed within Golden Gate National Recreation Area.
Golden Gate National Recreation Area
First "lit" in 1855, the Point Bonita Lighthouse long has worked to keep ships off the shoals as they entered San Francisco Bay. It wasn't always successful. The first edition of the lighthouse was located higher up on a hill, but proved to be too high, as the fog hid the light. The current location was chosen in 1877. It stands within the Golden Gate National Recreation Area.
