Point Bonita Lighthouse

The Point Bonita Lighthouse is the only US lighthouse at the end of a suspension bridge.

The Point Bonita Lighthouse is across the Golden Gate Bridge in the southwest tip of the Marin Headlands.  

It was constructed to protect mariners at the treacherous entrance to the San Francisco Bay, that claimed 300 shipwrecks during the Gold Rush era.

The only access to the Point Bonita Lighthouse is along a steep 1/2 mile trail, that passes through a handcarved tunnel and across a suspension bridge to the edge of the world!

5.  Walk through a hand-carved tunnel dug by Chinese workmen in the 1870s.

When the Point Bonita Lighthouse was moved to a lower location in 1877, Chinese workmen dug an 118-foot tunnel through hard rock to access it. The Old Point Bonita Lighthouse was originally built at a higher elevation in 1855, roughly 300 feet above sea level.  However it wasn't visible to ships at this higher elevation through the marine fog, and needed to be moved lower.

9.  Walk around the Point Bonita Lighthouse.

The Point Bonita Lighthouse is still an active national aid maintained by the U.S. Coast Guard, and is therefore not open for tours.  However, you can still watch its distinctive light pattern of 3 seconds on, 1 second off, and listen to the electric horn if fog reaches the lower elevation.

Continue down the stairs to the Lighthouse Keeper's Quarters buildings on the lower ledge.  Stand on the edge of the world with soaring views across the San Francisco Straits!
