Name and Location

The Lime Point Lighthouse is located at the mouth of San Francisco Bay in Marin County, California.

Construction and History

The Lime Point Lighthouse was constructed in 1924 as part of the U.S. Coast Guard's efforts to improve maritime safety along the West Coast. This historic lighthouse has been guiding mariners safely into and out of the bay for over a century.

Architecture and Materials

The lighthouse stands at an impressive height of 62 feet (19 meters) with a focal plane of 144 feet (44 meters). Its sturdy tower is built from reinforced concrete and features a distinctive white lantern room.

Light and Navigation

The Lime Point Lighthouse originally exhibited a fixed white light, but in 1934 it was modified to display a flashing white light every 15 seconds (Fl(3)W.15s). This unique light characteristic has been an essential aid to navigation for mariners traveling through the treacherous waters of San Francisco Bay.

The Lime Point Lighthouse is not open to the public for tours or visits due to its remote location and sensitive environmental conditions. However, visitors can access the surrounding area via the Bay Trail, which offers stunning views of the Pacific Ocean and San Francisco Bay.

Notable Views and Landscape

The lighthouse stands at the edge of a rugged coastline, where the Golden Gate National Recreation Area's Marin Headlands preserve extends. This unique environment is home to a variety of wildlife, including seals, sea lions, and over 200 species of birds.
