Closest to La Romana’s shores, Catalina is popular for its water sports, particularly diving and snorkeling. Portions of the beach are used for cruise ship excursions, but the entire stretch is open for the public to enjoy. It’s a stunner with its powder-fine white sand, calm waters, and lack of development. Catalina’s waters are abundant in coral reefs, including a “Living Museum of the Sea” following the discovery—after three centuries—of Captain Kidd’s shipwreck at 70 feet (21 meters), right off the island. Popular dive sites include the over 100 ft. Catalina Wall, and the Aquarium.
