Since Washington is almost 130 years old, it should come as no surprise that it’s full of abandoned places slowly being reclaimed by nature. But at Whidbey Island’s Fort Casey, the remnants of the old buildings are actually beautiful, especially the still intact Admiralty Head Lighthouse.

Fort Casey State Park is located in Coupeville on Whidbey Island.

Pat M / TripAdvisor Fort Casey was constructed in 1897 as part of the Triangle of Fire, which was meant to protect the Puget Sound from enemies by sea.

But when the airplane was invented in 1903, the need for the fort became obsolete.

These days, Fort Casey is a 476-acre marine camping park.

Robin S. / TripAdvisor And it makes a great day trip destination.

The highlight of the park is definitely the Admiralty Head Lighthouse.

canoer-jer / TripAdvisor Built in 1903, the lighthouse was in service until 1922 and has since been restored by Washington State Parks.

Walking around Fort Casey feels like going back in time.

This historic military fort is a must-see for every Washingtonian.
