Chehalis River campground with 40 standard and eight partial-hookup vehicle sites, showers, a trailer dump, and access to the Willapa Hills Trail.
Rainbow Falls State Park is a wooded campground on the Chehalis River west of Chehalis. The current park page lists 40 standard campsites and eight partial-hookup sites, plus separate hiker/biker and equestrian sites. Equipment up to 60 feet has limited availability. Showers and drinking water are listed, and the official campground map identifies a trailer dump. The park also connects with the Willapa Hills Trail. A kitchen shelter is closed through December 2026; the campground itself remains subject to the normal reservation and winter schedules.
Rainbow Falls State Park includes riverbank forest on the Chehalis River and access to the Willapa Hills Trail. River levels and swimming conditions vary; check current park alerts and fishing regulations before a visit.
Practical guidance assembled from current operator maps, park pages, and clearly identified community observations.
Sites along the Chehalis River (1–18) are the park highlight — the suspension bridge and falls are a 5-minute walk. Sites 19–35 are in a quieter forest setting. Very uncrowded compared to coastal parks; last-minute summer bookings are often possible. Excellent for kids who want to explore the river shallows and waterfall. A great off-the-beaten-path option in southwestern Washington.
