Rainbow Falls State Park is a 139-acre camping park with 3,400 feet of freshwater shoreline on the main stem of the Chehalis River. The park is a walker’s paradise. Miles of loamy trails wind through the forest and along the river, to a small cascade that throws rainbows of spray at the sun.
CampFinder checks Washington State Parks every 30 minutes, around the clock, and emails you when a booked-up night opens back up. That catches most cancellations, which sit open for hours; at the few campgrounds that refill in seconds it can miss the race. Set up a free availability alert for Rainbow Falls State Park.
