Rainbow Falls State Park

Rainbow Falls State Park provides about 3 miles of casual nature trails through a hillside forest and along the Chehalis River. The park contains one of the last stands of true old growth forest in the Chehalis Basin and Willapa Hills.

Rainbow Falls State Park straddles the Chehalis River and provides trails both along the river and through over 100 acres of hillside old growth forest, one of the last stands remaining in the upper Chehalis Basin and Willapa Hills. The trail is single-track through dense forest and undergrowth, passing many ancient cedars, Douglas fir, and western hemlock. Several  streams create small waterfalls over basalt outcrops. Rainbow Falls itself is a short steep drop over rock outcrops in the Chehalis River.
