If you’re visiting Washington State and want to see some of the country’s most beautiful coastal scenery, be sure to add Fort Casey State Park and Fort Flagler to your itinerary. These two parks are located in the so-called Triangle of Fire, which has seen more than its fair share of natural disasters.

Washington state parks are some of the best in the country, and this site features a blend of military history and outdoor adventures.

Fort Casey was built in the late 1800s as part of the country’s coastal defense system. The fort is now a state park open to the public for camping, picnicking, hiking, and beachcombing. Visitors can also explore the tunnels and bunkers that were once used to protect the coast from enemy attacks.

What is the Triangle of Fire, Washington?

Located on Whidbey Island in Northwest Washington, Fort Casey is a relic of the wars that our fathers and grandfathers fought on our behalf.

Constructed to protect the shores of the Western United States against a Pacific attack, the massive build-ups were deemed no longer necessary after World War II. Over time, they began to crumble and fall, but their history remained.

When active, Fort Casey was part of a group of forts called the “Triangle of Fire.” What makes Fort Casey unique, however, compared to the other two forts in the triangle, is that the fort itself is being restored.

Best of all, accessing the watchtowers, massive guns, and even the lighthouse that overlooks Admiralty Inlet at the forts is easy for kids and adults who may have a disability. However, there are still challenging climbs and warning signs that tell you that a fall could actually cause death. That means adventure awaits!

What Makes Fort Casey Special?

For a nominal fee, you get all-day access to this nearly 500-acre park and the other state parks on Whidbey Island. An annual pass allows unlimited access to all of Washington’s state parks if you plan an extended stay.

The expansive parade grounds are the first thing you’ll notice when entering Fort Casey. Even in the depths of winter, the lawn is green, lush, and inviting. Go ahead—let the kids find a hill and have a great time!

Exploring the ruins of the fort is self-guided all year. You can walk up the massive concrete steps that take you high in the air where watchmen once searched the waters for enemy ships and submarines. Crawl into a machine gun bunker and look through your grandfather’s eyes at what the world looked like during the war.

You can explore numerous storage facilities and underground bunkers and even walk down to the nearly 11,000 feet of rugged saltwater shoreline to search for hermit crabs if the tide is out!

When the clouds and fog clear away and the sun breaks through, the landscapes that surround Fort Casey are magnificent!

The Cascade Mountains are to the east, where Mount Baker stands tall in snow-capped brilliance for much of the year. The Olympics and the Admiralty Inlet are to the southwest, the passageway between Puget Sound and the Strait of Juan de Fuca.

If you’re visiting during a beautiful summer day, from late May to September 1, volunteers with the local Fort Casey Battalion also offer guided tours of the two 10-inch and two 3-inch historic guns that are proudly on display.

The Inlet is a major shipping channel as many cargo ships are headed into Seattle or leaving for the open Pacific waters. You’ll also see many Navy and Coast Guard ships in the area and if you’re lucky, a submarine with a whole civilian escort will churn through the waters!

How do I get to Fort Casey?

The other place to go is the reconstructed fort on Whidbey Island, Washington, where visitors must take a boat. The best approach to getting to the park from Seattle is by ferry across the Puget River to Port Townsend.

If you want to avoid paying for a ferry, you may drive north across the island towards Deception Pass Bridge and then travel south towards the Park. The journey takes between 2 and 3 hours, depending on your route.

You can take a ferry from Mukilteo to Clinton and drive about 10 minutes to this historic state park. If you’re coming from Whidbey Island, take the Keystone-Port Townsend Ferry and drive northeast for around 40 minutes.

Who owns Camp Casey?

In 2002, Seattle Pacific University acquired the Fort Casey Inn. The hotel is managed in conjunction with the Camp Casey Conference Center, which has various barracks, classrooms, auditoriums, mess rooms, and gyms.

The camp hosts various events, including children’s camps, business retreats, and community festivals within this historic state park.

If you schedule your visit well in advance, you can reserve one of the four pull-through campsites on the beach! Make sure you bring your boat as well, as two saltwater launches are available for a minimal fee.

If your stay is extended, you might also consider visiting Fort Warden and Fort Flagler, the other two forts that compose the old Triangle of Fire.

Many men walked the shores of Fort Casey to ensure the United States’ freedoms were protected. Touch the walls, look through the sights of a 10-inch gun, and you’ll glimpse those sacrifices when you visit this unique Washington location.
