Barbuda, formerly Dulcina, lies 25 miles (40 km) north of Antigua. It is a largely undeveloped coral island, flat and well-wooded without streams or lakes and receives less rainfall than Antigua. The only town is Codrington set on a lagoon in the west of the island. Activities on Barbuda include beachcombing (on the northeastern Atlantic coast), fishing, snorkeling, diving and, at the island's resorts, golf and tennis. Points of interest include the Frigate Bird Sanctuary, the pink and white sand beaches, and an abundance of shipwrecks and beautiful reefs.
