Getting there

Fossil Falls sits about 23 miles north of Inyokern in Inyo County. Navigate to the coordinates 35.96976, -117.90902, which mark the waterfall itself; the trailhead or parking area may be some distance away. Reviewers mention "rocky path", so plan for uneven or steep ground.

Open directions in Google Maps or Apple Maps, or view the map on the Fossil Falls listing. Navigation apps sometimes route onto seasonal forest roads, so check road status if you are heading into the mountains.

California's falls are spread across national parks, national forests, state parks and county or regional open space, with a few on tribal land. In Yosemite and other heavily visited parks, the National Park Service has used vehicle reservation systems during busy periods in recent years, so checking current entry requirements before travel is wise. Many trailheads in Southern California fill early on weekends. The most serious hazards are swift, cold snowmelt and slick granite: people regularly die after slipping into rivers above waterfalls in the Sierra, especially in late spring. In the southern mountains and deserts, sudden storms can produce flash floods in narrow canyons, and summer heat makes midday hiking risky. Wildfire closures can also affect forest access in late summer and autumn.

What to bring

This checklist is tailored to Fossil Falls based on what visitors report and the conditions typical of California. For the complete list, see our waterfall hike packing guide.

• Offline map and coordinates. Save 35.96976, -117.90902 and download offline maps; cell service is often weak near waterfalls.
• Shoes with real grip. Rock near falling water stays wet and slick even in dry weather.
• Water and a snack. More than you think you need, even for a short walk.
• A light rain layer. Spray from the falls and quick-moving showers can soak you.
• Trekking poles. Helpful on steep or rocky sections that reviewers mention.
• Camera and a small tripod. Visitors have shared 851 photos of it; a tripod lets you shoot silky water in low light.
• Headlamp. In case your visit runs later than planned; check sunset time in the conditions panel above.

How to prepare

Timing

Timing depends on elevation. Low-elevation coastal and Southern California falls peak during and just after winter storms, typically January through April, and often fade by June. Sierra Nevada falls follow the snowpack: in Yosemite, flows usually build in April, peak in May and June, and decline through July, with some falls dry by late summer in an average year. Big snow years extend the season; drought years shorten it sharply. Spring-fed falls in Shasta and Siskiyou counties are the exception and are worthwhile in any season. High Sierra roads such as the Tioga Road and those to the eastern trailheads usually remain closed into late spring, and summer weekends bring heavy crowds to Yosemite Valley and other well-known sites. 160 Google reviews suggest steady but manageable traffic outside peak weekends.

Safety

Stay behind railings and off wet rock, never climb on the falls, and keep children within arm's reach near the water. Check the weather panel above for flood or storm alerts before you set out; water levels can rise fast after upstream rain. Our waterfall safety guide covers the most common hazards.

Respect the place

Pack out everything you bring, stay on established paths to limit erosion, and leave rocks and plants where they are. See Leave No Trace at waterfalls.

History of the area

Fossil Falls was entered in the Geographic Names Information System on June 1, 1995, and it appears on the USGS Little Lake 7.5-minute topographic map.

Its neighbors on the map tell the story of the surrounding land: Red Hill (summit, 1.3 mi), Little Lake (lake, 1.6 mi), and Little Lake Canyon (valley, 1.8 mi).

Eastern Sierra and Owens Valley. The Sierra's eastern escarpment rises abruptly from the Great Basin, and its creeks fall steeply toward Bridgeport, Mammoth Lakes and Big Pine. Snowmelt feeds most of these falls, so they run hardest in early summer and shrink in autumn. Bridgeport and the June Lake and Mammoth areas are the main bases for exploring them. In Inyo County, Fossil Falls is an unusual dry fall: a polished basalt chute carved by an ancient river that no longer flows there, set in desert volcanic terrain south of the Owens Valley.
