Schafer State Park is a 119acre Washington state park in the Satsop Hills of Mason County. The park sits on the Satsop River midway between Olympia and Aberdeen. The park offers camping, two miles of hiking trails, fishing (especially for steelhead), swimming, birdwatching, interpretive activities, wildlife viewing, and horseshoes. The park's abundance of historic structures led to its being added to the National Register of Historic Places in 2010.
