Although the exact location of the fort erected by the British in 1736 remains uncertain, the island still bears its name. In its pre-WWII glory days, flappers flocked here to the ritzy Ribault Club, built in 1928, for lavish Gatsby-esque bashes. Now housing the visitor center, the meticulously restored mansion flaunts grand archways and three dozen French doors. It's the starting point of the 4.4-mile Saturiwa loop trail, which you can walk, bike or drive.
Enormous shell middens date the island's habitation by the Timucuan tribespeople to over 4000 years ago.
