Farol da Guia (Guia's lighthouse) presides a scuba diving site on a small bay right across the lighthouse, with easy access by land. The rocky massif that houses this small bay on the west side creates a natural protection (a sort of protective jetty) from the prevailing north quadrant winds. While the site can sometimes become monotonous when silted, it can also offer great dives at times as it strips a series of very cut rocks with cracks and huge holes that quickly become a shelter for many species of marine organisms. When the conditions are right, divers can find traces of a wreck (an iron fishing vessel) with its big plates and other small structures totally exposed.
At the Southeast corner of the bay divers can find a kind of submerged spur of high rock, with well defined paths and large holes. To the South of this spur divers can also find two large irons that could possibly belong to the old tuna frames of former fishing vessels. This diving site is often visited for diving courses, underwater photography and night dives.
