Point Bonita Lighthouse is a lighthouse located at Point Bonita at the San Francisco Bay entrance in the Marin Headlands near Sausalito, California. Point Bonita was the last manned lighthouse on the California coast. It was added to the National Register of Historic Places in 1991. [3]
More than 300 boats ran aground near the Golden Gate during the California Gold Rush years, requiring a lighthouse.
The original Point Bonita Lighthouse, a 56-foot (17 m) brick tower, was built in 1855 at 306 feet (93 m) above sea level with a second order Fresnel lens. This was too high. Unlike the East Coast of the United States, the West Coast has dense high fog, which leaves lower elevations clear. Since the original light was so high, it was often cloaked in fog and could not be seen from the sea. As a result, the lighthouse was moved to its current location at 124 feet (38 m) above sea level in 1877. To access the new site, a 118-foot (36 m) long tunnel was hand carved through hard rock. [4]
The lighthouse had the first fog signal on the West Coast, in the form of a 24-pounder siege gun.
Up until 1940 the lighthouse could be reached by a trail, but erosion caused the trail to crumble into the sea. A wooden walkway was installed, but when that became treacherous a suspension bridge was built in 1954. This is the only lighthouse in the United States which can only be reached by a suspension bridge.
The suspension bridge underwent repairs in 1979 and again in 1991, but the metal components were not able to stand up to the sea spray. As a result, the suspension bridge to the light house was closed to public access on January 6, 2010. According to the Federal Highway Administration, the bridge, which was 56 years old, had started to rust. It was replaced by a new span which opened April 13, 2012.
The new bridge construction cost a little over $1 million. It is made of tropical hardwood with steel suspension cables and attachments. [5]
The United States Coast Guard currently maintains the light and fog signal.
The lighthouse is accessible to the public during limited hours (12:30–3:30 p.m.) on Sundays and Mondays, [6] as well as on ranger-led interpretive sunset hikes, which requires a sign-up. Access to the bridge is barred at other times by a metal door on the shore end of the tunnel.
The lighthouse closed in March 2020 for the COVID-19 pandemic, but resumed tours two years later on February 20, 2022. [7]
On the television show Murder in the First the lighthouse was a setting at the end of the second-season episode "Schizofrenzy".
The lighthouse can be found in the video game Watch Dogs 2 .

Alcatraz Island Lighthouse is a lighthouse—the first one built on the U.S. West Coast—located on Alcatraz Island in California's San Francisco Bay. It is located at the southern end of the island near the entrance to the prison. The first light house on the island was completed in 1854, and served the bay during its time as a Citadel and military prison. It was replaced by a taller concrete tower built in 1909 to the south of the original one which was demolished after it was damaged due to earthquake in 1906. The automation of the lighthouse with a modern beacon took place in 1963, the year Alcatraz closed as the Alcatraz Federal Penitentiary. It is the oldest light station on the island with a modern beacon and is part of the museum on the island. Although when viewed from afar it easily looks the tallest structure on Alcatraz, it is actually shorter than the Alcatraz Water Tower, but as it lies on higher ground it looks much taller.

When the weather affords low-visibility, one can hear the station's fog horn – sounding a single blast for two seconds, and repeating every 15 seconds – as it seems to call out for its nearly-identical closest neighbor, the Wood End Light.
