Vacations should be about beaches. These islands have some of the most memorable. On Anegada, you can walk miles without seeing another soul, then, miraculously, there appears a shady little beach bar just in the nick of time. At the Baths, on Virgin Gorda, you will find a beach that is one of the Caribbean's natural wonders. Cane Garden Bay, on Tortola, is a beach totally surrounded by nightlife, and White Bay on Jost Van Dyke is the world's best Saturday afternoon.
