Ideal Weather, All Year Round

The Island lies on the Intracoastal Waterway and encompasses 42 square miles of semi-tropical, Lowcountry geography, including unspoiled sea marshes, creeks and lagoons, heavily wooded forests of tall pines, palmettos, magnolias, and live oaks, and 12 miles of wide Atlantic beaches.
