What is the Triangle of Fire, Washington?

Fort Casey Lead

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.

Fort Casey, when active, 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!
