Point Diablo is located roughly midway between Point Bonita and Lime Point on the northern side of the Golden Gate. The point protrudes some 600 feet into the waters from the Marin Headlands, making the point, according to the Lighthouse Service, "a dangerous menace to vessels entering San Francisco Bay in foggy weather."
In 1923, the Lighthouse Service decided to mark this navigational hazard, and a small white shack with a pitched red roof was placed on the sloping point some eighty feet above the water. The structure housed two lens lanterns and a 12-inch electric siren.
An array of solar panels now powers the modern beacon positioned atop the shack. The light flashes every six seconds, and when necessary the fog signal alerts mariners to the presence of menacing Point Diablo.
