Millersylvania State Park is ideally located in a country setting and forested region of southern Olympia, with an easy drive to the state capital and historic downtown Olympia. The park is nestled in broad stands of old-growth cedar and fir trees and is filled with hiking and biking trails. Deep Lake offers boating, fishing, and swimming.
