Sea Islands Travel Guide, USA. Tourism. Vacation Packages. Guarding St. Simons to the east is Sea Island, a thin Holocene barrier island that serves as a resort and home for the rich. Founded in the Roaring Twenties by Sea Island Company owners Howard Coffin and Alfred (Bill) Jones Sr., the island boasts a world-famous resort, The Cloister Hotel, and a resident community of grand estates with carefully manicured lawns and gardens. The public is allowed to drive the public roads of the island and take a stroll through the hotel, but access to the beach is unfortunately limited to residents and guests. However, if you can afford to stay at The Cloister Hotel, the world is indeed your oyster, with 54 holes of golf, 17 tennis courts, a spa, two pools, four restaurants, horseback riding, shooting school, sailing, biking, nature tours, dance lessons, scuba lessons, surf and deep-sea fishing, and 4.5 miles of beach offered for your pleasure.
