Catalina Island is home to a diverse ecosystem of sand dunes, mangroves, and reefs populated by many species of sea birds and tropical fish. The island’s main draws are its white sandy beaches and its beautiful underwater ecosystem. Snorkeling and scuba diving are particularly good here, and the Wall and the Aquarium are two of the top dive sites.
Tours from the Dominican Republic’s mainland (originating in Bayahibe, Punta Cana, La Romana, or even as far-flung as Santo Domingo) are plentiful and usually last all day. Some tours combine a trip to Catalina Island with visits to other area highlights such as Altos de Chavon, the more populated Saona Island, or Casa de Campo. Snorkeling tours and scuba diving tours usually include use of equipment.
