Natural Features and SceneryThe Chehalis River flows over rugged basalt outcrops, forming small rapids and clear pools popular for swimming and wading. Second-growth evergreens mix with scattered old-growth firs, and sword ferns blanket the forest floor. The namesake falls are modest. More a cascade than a drop. And shrink to a trickle by late summer. A large sunny meadow anchors the day-use area. At 289 feet elevation, the terrain is gentle riparian lowland typical of western Washington's river corridors.

Go if

Families after river swimming and a forested base camp will do well here, especially on river-adjacent sites booked early. The Willapa Hills Trail connection suits bikers and hikers who don't need big elevation.

Skip if

Sites far from the single main restroom building mean a long night walk, and summer weekends get loud. Large RVs should know the entrance road is narrow with tight turn-ins that catch rigs off guard.
