In addition to the mainland’s sparkling beaches, the DR boasts multiple offshore cayes with an even more stunning sea and sand environment. Hop on a catamaran sail to breathtaking Saona or Catalina islands, home to the Caribbean’s longest natural pool, and beaches stretching as far as the eye can see against iridescent turquoise waters. Cayo Arena, off the coast of Puerto Plata, is ideal for a snorkeling trip. Off the coast of Samaná, Cayo Levantado is a perfect lunch and swim escape—often included in tours of Los Haitises, but you can also overnight at the on—site, luxury resort. Off the coast of Montecristi are the most off-the-beaten track cays of the Siete Hermanos.

Island excursions are offered year-round, and are particularly enjoyable during the summer season, when crowds are fewer.
