Accessible only by ferry, this barrier island is 45 minutes away from downtown Charleston and feels far away from the comforts of civilization. A good way to see the birds of this untouched island, and perhaps a playful dolphin if you’re lucky, is on a guided paddling tour. Comb the beach for shells, walk Boneyard Beach where a forest is being recalled by the sea, or track foxes, bobcat, and deer.
