Pigeon Key

Pigeon Key is a tiny island beneath the Old Seven Mile Bridge, just west of Marathon. In the early 1900s it housed workers building Henry Flagler’s Overseas Railroad, and several of the original buildings still stand as a museum and marine science center.

Visitors reach the island on guided tours by train, on foot or by bike along the restored bridge, and can snorkel and picnic once there. Check the tour schedule and departure point before you go.
