Point Bonita Lighthouse, located at the South Western tip of the Marin headlands, is an active lighthouse with a rich history. The lighthouse was the 3rd lighthouse on the West Coast and was first built in 1855.
The short (0.3 miles) trail from the parking lot offers spectacular views on the Pacific Cliffs.
Be careful, especially with little kids, since the trail and next to a steep drop off.
Point Bonita is easily reachable by car North of San Francisco, via a scenic road which includes crossing the Golden Gate Bridge. This is a highly recommended half day trip for San Francisco Visitors.
