About
St Marys is the gateway to Cumberland Island, Georgia's largest and southernmost barrier island. Here pristine maritime forests, undeveloped beaches and wide marshes whisper the stories of both man and nature. Natives, missionaries, enslaved African Americans and Wealthy Industrialists all walked here. Cumberland Island is also home to over 9,800 acres of Congressionally designated Wilderness.
