Moran State Park

Moran State Park was named for Robert Moran, the Seattle Mayor and ship builder who provided the land for the park. The residence he built, Rosario, continues to be one of the San Juans premier resorts. At nearly 5,000 acres, Moran State Park is one of the largest in Washington State. The park contains five lakes, over 30 miles of trails and more than 150 campsites.
