Although the exact location of the fort that was erected here by the British in 1736 remains uncertain, the island still bears its name. In pre-WW2 glory days, the island raged, when flappers flocked to the ritzy Ribault Club, built in 1928, for lavish Gatsby-esque bashes. Today housing the Visitor Center, the meticulously restored mansion flaunts grand archways and three dozen sets of cypress 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 Native Americans to over 4000 years ago. It is protected by the Timucuan Ecological and Historic Preserve.
