Fort Casey Historical State Park
RV Guide


Just under 1,000 acres, Fort Casey Historical State Park is not an average marine park. Established in the late 1800s, Fort Casey is one of three forts that were known as the "Triangle of Fire." Together, these forts defended the sole entrance to Washington's Puget Sound. During World War I and World War II, the area was used as a military training facility until the mid-1940s when advancements in more mobile forms of attack, such as airplanes, rendered the fort's defenses obsolete and it was decommissioned. The fort and surrounding area were acquired by Washington State Parks in 1955. Today, the historic military fort with bunkers and batteries still stands as well as the 1903 vintage lighthouse. Park visitors can visit both historical structures to learn more about Fort Casey's rich history.

Not only is Fort Casey Historical State Park full of fun stories, but it is also a place of immense beauty. Set among douglas fir, hemlock, spruce, alder, cherry and apple trees, the park is a great place for hiking and enjoying some of Washington's natural beauty. The campground offers views of the Admiralty Inlet and the Strait of Juan de Fuca. 10,810 feet of saltwater shoreline form a popular recreation site where activities include fishing for salmon, boating, swimming, and picnicking to name a few. Keen-eyed visitors can spot all sorts of wildlife, including chipmunks, foxes, otters, and deer, while birders will be more than thrilled to sight eagles, gulls, hawks, and herons hunting and nesting near the shore.
