If you prefer your solitude with a mint julep, consider Eagle Island. A 15-minute boat ride speeds guests from Darien, Georgia, to this private ten-acre kingdom topped with a ten-bed reclaimed-cypress lodge (from $400; privateislandsofgeorgia.com). Take the resident kayak for a spin, spy on nesting bald eagles, pluck dinner from the blue-crab traps—or just settle for a julep in the hot tub.
