"Cumberland Island National Seashore is the largest and southernmost barrier island in Georgia, offering guests over 17 miles of secluded white, sandy beaches. Wild horses and other island wildlife roam freely throughout the ruins and along the beach. Glimpses of the Carnegie lifestyle can be easily imagined throughout the ruins of Dungeness, abandoned luxury vehicles, Plum Orchard, and Greyfield Inn. Located just off the Georgia Coast of St. Marys. Island is accessible by ferry only.'Fantastic subject.
