Lake Sylvia State Park is a wooded 252-acre camping park with 15,000 feet of freshwater shoreline. Set in a former logging camp above the historic town of Montesano, park life revolves around a large swimming and fishing lake that draws families to its shores all summer long, and the rustic charm of the park makes for excellent day and group camping trips.
