Trillium Falls is in Prairie Creek, off Davidson Road. Really nice half-day trip.

One of the newer trails in the park, this route is more notable for its noble redwoods and proximity to the Prairie Creek elk herd than for its small waterfall and scattering of trilliums. A springtime visit, with all four features present, is perhaps the best time for this hike, but it offers enjoyment—only a half mile from Highway 101—year-round.
