Fort Casey State Park


Welcome to Fort Casey State Park, a 467-acre marine camping park, three miles from Coupeville on Whidbey Island in Washington’s Puget Sound. Set among Douglas fir, hemlock, spruce, alder, cherry and apple trees, the campground offers views of the Admiralty Inlet and the Strait of Juan de Fuca.

Just a short walk away you’ll find Fort Casey’s old military fort, a place of immense historical beauty. Established in the late 1800s, the park was used as a training facility until the mid-1940s and includes a 1903 vintage lighthouse, a military fort with bunkers and batteries, and four historic guns constructed by the United States Army.

But it’s not just the incredible history that attracts campers and day visitors to this fantastic state park. You can also explore Keystone Spit and Crocket Lake as well as 10,810 feet of saltwater shoreline. Outdoor recreation is popular here - fish for salmon beside the ferry terminal, fly your kite on the endless greens next to the fort, and visit the interpretive center and gift shop tucked away inside the old lighthouse. Picnics are also popular because of the park’s stunning natural beauty – particularly in the springtime when you’ll see rhododendrons, roses, ferns, and foxgloves. Keep an eye out for all sorts of wildlife, such as chipmunks, fox, otters, and deer, while birders can look out for eagles, gulls, hawks, and herons.
