Rainbow Falls State Park - Washington State Parks

Located along the Chehalis River, named after scenic Rainbow Falls, this park has hiking, camping, swimming, fishing, and fields for sports. The majority of the park is on the north side of the river, while all the hiking is on the south side. No bridge crosses the river in the park due to them washing out in 2007.
