Just 600 feet off the north shore of Nassau, Paradise Island is celebrated for its long stretches of pearly white sand. If you feel like jogging away from the crowds at Atlantis, head to Shell Beach on the southeastern shores of the island. For a longer jaunt, take a 20-minute boat ride to Blue Lagoon Island. Wade waist-deep in the shallow waters off the beach, and you might soon be wrapped in a wet suit of tame stingrays.
