Little San Salvador Island, also called Half Moon Cay, is a tiny private island in the Bahamas. Accessible by cruise ship, it's known for the long, crescent-shaped Half Moon Beach. Luxury cabanas dot the beachfront, which gives way to trail-lined country rich in birdlife. Half Moon Lagoon Aqua Park has water slides and playgrounds. Stingray Cove, a lagoon enclosure, is home to tame stingrays.
