Cumberland Island National Seashore

Cumberland Island, Georgia's largest barrier island, is accessible only by ferry and supports a wild population of feral horses descended from colonial-era stock. The island's interior holds maritime forest, freshwater marshes, and the ruins of Dungeness, the Carnegies' late-nineteenth-century mansion. The undeveloped Atlantic beach, stretching seventeen miles, remains one of the most isolated stretches of barrier island coastline on the eastern seaboard.
