Long Ridge Falls is a 20-foot roadside waterfall located right along FR 244 (White Oak Gap Road) beyond the trailhead for Raven Cliff Falls and Davis Creek. The sliding drop of Long Ridge Falls isn't especially impressive, but it's notable for the easily-viewed roadside location. Being located on a small tributary of Dover Creek, this waterfall is best seen in wet weather.
