The land that is now Dugualla State Park was originally owned by the Department of Natural Resources as part of the School Lands Trust. In 1992 Washington State Parks acquired the 586 acre property to prevent it from being logged. Dugualla State Park is managed as a satellite of Deception Pass State Park in collaboration with Island County.
Dugualla State Park features several miles of trails (see map below), and over a mile of shoreline.
