Since Barbuda is so isolated, and transport can be tricky, one great way to explore the island is with the Barbuda Express Day Tour. The trip, which costs around $160, takes in all the island's major sites. These include a boat ride through the frigate bird sanctuary, exploring the east-coast caves that's walls are covered in ancient Arawak drawings, and a fresh lobster lunch on one of Barbuda's famed and secluded pink sand beaches. This same company also runs a once-daily catamaran ferry between Antigua and Barbuda. The trip takes 90-minutes. Boat trips depart from the ferry landing in the harbor in Codrington, the only village on the island. Also in the vicinity of the ferry landing is the 56ft-high Martello Tower, which is a former fortified looking out station that resembles an old sugar mill from a distance, and makes for a classic Barbuda photograph.
