Fort Flagler

Fort Flagler Professional Review and Guide

"One of several grand military installations originally established to protect Puget Sound from foreign invaders, Fort Flagler—like the others—never saw combat. In the 1950s these forts were converted to state parks. At 780 acres, Fort Flagler on the northern tip of Marrowstone Island is the largest, consisting of over 3.5 miles of shoreline. It offers fine beach hiking and miles of trails weaving through quiet forest and historical grounds.

With more than 7 miles of trail and 3.5 miles of coastline, Fort Flagler offers many hiking options. The following loop samples a few of the many facets of this wonderful park."

I think I started on the trail, I think I was on the trail, but we all just turned into Beachcombers. Definitely bring a kite if you come.
