Visitors can take a boat trip around the Port Est from the Commerce marina; you will see the tug base, workshops, locks, the sugar terminal, the refinery and oil wharfs, etc. If you are on foot, visit the 59m-high lighthouse with a panoramic view of the port and, opposite the Musée Portuaire, the Duchesse Anne, a three-master, the Sandettie lightship and the Guilde barge.
