Point Bonita Lighthouse is located in the Golden Gate National Recreation Area in Marin County, California. It was first established in 1855 and is now one of the oldest lighthouses on the West Coast. The lighthouse stands on a cliff at the entrance to the San Francisco Bay and is a popular tourist destination for its breathtaking views and rich history.

The lighthouse is accessible via a 300-foot suspension bridge, which was added in 1954 to replace the original staircase. The bridge provides a unique experience for visitors as they make their way across to the lighthouse, offering stunning views of the Bay Area and the Pacific Ocean.

Point Bonita Lighthouse is also a prime example of the technological advancements made in lighthouse construction during the 19th century. The lighthouse's Fresnel lens is still in use today and provides a beam of light that can be seen up to 18 nautical miles away.

Visitors can tour the lighthouse and learn about its history and significance through exhibits and guided tours. The lighthouse is open to the public on weekends and also offers guided tours during the week by appointment.
