Mile Rocks Light is a lighthouse in City and County of San Francisco, California. It sits roughly 6.0 km (3.7 mi) NNW of Parkside. It dates from 1906.
Mile Rocks Lighthouse is located on a rock about 2.3 miles (3.7 km) southwest of the Golden Gate Bridge, off of Lands End in San Francisco, California. It was completed in 1906, replacing a nearby bell buoy. In 1966, the light was automated, and the original 85 ft (26 m) tower of the lighthouse was demolished and replaced by a helipad. The lighthouse was at one time painted with alternating red and white rings, but as of 2017, the lighthouse is painted plain white.From the Wikipedia article “Mile Rocks Lighthouse”, licensed under CC BY-SA 4.0.

Golden hour & blue hour by month
Lighthouses work at both ends of the day: blue hour when the beacon is lit, and golden hour when white towers take on warm tones.

Milky Way & night sky
From Mile Rocks 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 7 (suburban / urban transition), so expect visible sky glow; drive away from towns for better results.

Window when the galactic core is at least 10° high during astronomical darkness on the 15th of each month. Pick nights within a few days of the new moon. Plan exact nights with the Milky Way planner.
Estimated sky darkness: 7 Bortle 7 — Suburban / urban transition. The whole sky has a grey-white glow; the Milky Way is invisible to the eye. Modeled zenith brightness ≈ 18.46 mag/arcsec².
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
- 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.
- During blue hour, use 5–15 second exposures to capture the beam; check whether the light is still active.
- Shoot from the beach or a jetty to place the tower against open sky and sea.
- Tell someone where you're going in remote areas and carry the ten essentials.
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.
Tides
The nearest NOAA tide prediction station is Ocean Beach, outer coast, 2.0 km (1.2 mi) away. Low tide often reveals tide pools, wet-sand reflections and sea stacks.
