Fort Flagler Historical State Park is a 1,454-acre marine camping park surrounded on three sides by 19,100 feet of saltwater shoreline. The group of forts once known as the “Triangle of Fire” (made up of Fort Flagler, Fort Worden and Fort Casey) is a must-see for military, armament and maritime enthusiasts. Fort Flagler’s off-the-beaten track location and its wide, manicured former parade lawns make it a winning destination.
