Schafer State Park is a 122 acre public recreation area along the Satsop River in the Satsop Hills of Mason County, Washington, midway between Olympia and Aberdeen. It offers camping, two miles of hiking trails, fishing, especially for steelhead, swimming, birdwatching, interpretive activities, wildlife viewing, and horseshoes. Its abundance of historic structures led to its inclusion on the National Register of Historic Places in 2010.
