Shark's Friends is a professional outfit with dive masters speaking English, Italian and German. The center, on the beach between Brisas Santa Lucía and Gran Club Santa Lucía, offers dives, open-water certification and shark feeds.
November through January is the best time for the shark feeding or dive boats go out every two hours between 9am and 3pm daily (though the last dive is contingent on demand). The open-water course costs CUC$315; a resort course is CUC$74. It also has snorkeling excursions.
