Barbuda Only 62 square-miles, Antigua’s little sister captivates with miles of pink sand at Low Bay (the 17-mile strand where Lighthouse Bay resort, the island’s best-known hotel, sits) and Dulcina Bay, which borders the pier you’ll arrive. But before you spread out your beach blanket, take an excursion through the sleepy town to Codrington Lagoon, a marine sanctuary where rare frigate birds roost.
