Alcatraz Island Light — a lighthouse in City and County of San Francisco, California — is a classic subject for landscape photographers. It lies in or next to Alcatraz Island, so park hours, fees and rules apply. It sits roughly 3.5 km (2.2 mi) NNW of Chinatown. Its recorded tower height is about 26 m (85 ft). It dates from 1854.

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 (95 feet (29 m) above mean sea level) 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...From the Wikipedia article “Alcatraz Island Lighthouse”, licensed under CC BY-SA 4.0.

Milky Way & night sky

From Alcatraz Island Light, the Milky Way core is visible in a dark sky from March through September. June gives the longest window (about 5.3 hours on a moonless night), and the core peaks around 23° above the southern horizon. Our light-pollution model puts the sky at about Bortle 8 (city sky), so expect visible sky glow; drive away from towns for better results.

Weather & best season

Long-term NASA satellite data for this area show October as the clearest month (about 44% average cloud cover) and December as the cloudiest (59%). September is the warmest month and January the coldest, which matters for gear, snow access and how long batteries last at night.

Photography tips for this lighthouse

  • Stormy weather and crashing surf add drama; keep a safe distance from waves on rocks and piers.
  • A telephoto from across a bay compresses the tower against cliffs or the moon.
  • Many lighthouses are on private or Coast Guard property — check public access and opening hours.
  • Moonrise or the Milky Way over the tower makes a classic night composition; plan with the azimuth tables.
  • Check road and trail conditions with the managing agency before you go.

Season: Summer brings open towers and tours; autumn and winter offer storms, fewer crowds and lower sun angles.

Suggested gear: Tripod, Telephoto lens, ND filter for smooth water, Rain cover. Work out exposures with the depth of field, ND filter and NPF rule calculators.

Permits, drones & access

National Park Service rules. Under federal law (54 U.S.C. 100905), still photography in National Park Service areas needs a permit only when it (1) takes place where members of the public are not allowed, (2) uses models, sets or props that are not part of the location's natural or cultural resources or administrative facilities, or (3) would cause the park to incur additional administrative costs to monitor the activity. Ordinary visitor and most landscape photography needs no permit. Commercial filming rules are separate and have changed in recent years — confirm current requirements with the park before a paid shoot.

Drones: Launching, landing or operating unmanned aircraft (drones) is prohibited in National Park Service units under a 2014 Superintendent's closure (36 CFR 1.5), except where a park has issued specific written approval. Flying from outside the boundary over park land can also violate park rules and disturb wildlife.
