An island tour that covers all of Antigua’s highlights includes a visit to English Harbor, the historic district that houses Nelson’s Dockyard, where salty seagoing vessels and luxury yachts meet in shimmering waters. With its bird’s-eye view of the entire island, Shirley Heights is an excellent place to watch the sunset. Barbuda, a series of gorgeous sandy beaches only a few miles away, offers a more laid-back attitude than Antigua. Opportunities to go out on the sea abound on both islands, from yachting excursions to snorkeling and swimming.
