Anegada, Antigua and Barbuda
This coral atoll peaks at a mere 28 feet above sea level, giving it the nickname "the drowned island." By the time you see it on the ferry from Tortola, you're there. The first thing you'll notice: Few others are. Just 300 people live on Anegada's 15 square miles. So get lost in it. "Jump on a scooter and head to the north shore — you can walk for miles on white sand without seeing anyone," says Simon Scott, co-author of Cruising Guide to the Virgin Islands. Once you're tired of the silence, or of snorkeling the U-shaped reef that rings the island, pull up a seat on the Anegada Reef Hotel's back porch, where at twilight, lobsters fished a stone's throw from the dock are cooked over oil-drum grills. "It's just a laid-back experience unto itself," says Scott.
Getting there: Fly into St. Thomas, then take a 50-minute ferry to Tortola; from there a 75-minute ferry runs to Anegada three days a week.
