Red Rock Falls is a roughly 20-foot waterfall on Lewis Creek in Sierra National Forest between Oakhurst and Yosemite, reached via the Lewis Creek National Recreation Trail. The trail also passes the taller Corlieu Falls and is best in spring during high flow.
At 20 ft, it stands above roughly 12% of the 775 documented falls in this guide.
The falls are fed by Lewis Creek. You'll find it in Madera, California. It is protected within Sierra National Forest (USFS).
This is a moderate hike waterfall: a longer day hike, roughly one to several miles each way. Plan for a moderate hike; sturdy shoes, water, and a little time on the trail are worth bringing. The walk to the main viewpoint runs about 3 miles round trip. Base a visit out of Oakhurst, the closest town.
When to go: Spring (high flow). Expect the strongest flow in spring and after big storms, with a quieter trickle by late summer; confirm current conditions with the land manager before committing to the drive.
