Tourist attraction
Point Bonita Lighthouse
San Francisco, Bay entrance in the Marin Headlands, Sausalito, CA 94965, USA
Active cliffside lighthouse reached via a hand-carved tunnel and a swaying suspension bridge above the surf.
This guide to Point Bonita Lighthouse in San Francisco follows Edward Maloney, the army sergeant tasked with firing an hourly fog cannon by hand through sleepless nights in 1855, and the discovery that the signal did not work. It traces the lighthouse's move down to sea level in 1877 and the tunnel laborers carved through solid rock to reach it. Best heard at the tunnel entrance, before you start toward the light itself.
