From the National Park Service
Marin Headlands, Golden Gate National Recreation Area Welcome to Black Sands Beach, a hidden gem nestled within the rugged beauty of the Marin Headlands. To reach the beach you will take Upper Fisherman's Trail, a steep and challenging trail that provides access to this secluded spot known for its dark, coarse sands and stunning coastal views. This hike is recommended for experienced hikers who are prepared for a short but strenuous descent.
Distance The Upper Fisherman’s Trail spans approximately 0.3 miles (0.5 km) one way. Though short in distance, the trail’s steepness makes it a more demanding hike than the distance suggests.
Estimated Time Plan for about 20 to 30 minutes each way, depending on your pace and comfort with steep terrain. The return trip may take longer due to the challenging ascent.
Elevation Gain Starting from the trailhead, you will descend approximately 300 feet (91 meters) to reach Black Sands Beach. This elevation change is quite rapid over the short distance, making the trail steep and requiring careful footing.

Milky Way & night sky
From Black Sands Beach, 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.

Photography tips for this beach
- Slow shutter speeds (0.5–2 s) turn receding waves into streaks that lead toward the horizon.
- Watch for sneaker waves; never turn your back on the ocean on exposed coasts.
- Salt spray coats lenses quickly; wipe often and rinse gear afterward.
- Fog and marine layers can make minimalist images; don't give up on grey days.
- Time visits around low tide to reveal tide pools, sea stacks and reflective sand — check the tide widget below.
- Tell someone where you're going in remote areas and carry the ten essentials.
Season: Winter storms bring dramatic surf on Pacific coasts; summer and autumn sunsets are popular on Atlantic and Gulf beaches.
Suggested gear: Tripod, ND filters, Rain cover, Lens cloths. 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.
Tides
The nearest NOAA tide prediction station is Point Bonita, Bonita Cove, 1.8 km (1.1 mi) away. Low tide often reveals tide pools, wet-sand reflections and sea stacks.
