This beach at the northwestern tip of Mayreau takes top honors—it's an exquisite, 2½-mile-long (4-km-long) crescent of powdery white sand shaded by perfectly spaced palms, sea grape trees, and flowering bushes. It's a popular anchorage for the yachting crowd, as well as for day trips en route to or from the Tobago Cays. Amenities: none. Best for: snorkeling; swimming.
