La Caleta Underwater National Park, one of the first in the region, is a popular dive site located close to Santo Domingo. It’s known for its multiple shipwrecks, but also for its abundant marine life ready to be explored by all levels of divers, from beginner to advanced. Depths go from six meters (20 feet) to 180 meters (591 feet), over an area stretching 10 km² (four square miles) from Las Golondrinas Cave to Punta Caucedo. La Caleta’s irregular topography includes three defined terraces, underwater caves, and well-known shipwrecks. A variety of corals and schools of colorful critters thrive here, using the reefs as shelter and food source, including grouper, balloon fish, rays, lionfish, octopuses, and turtles. Among the more popular shipwrecks is the Hickory, a 1984 ship located at about 18 meters (60 feet) deep, submerged in 1984 by a group of submarine researchers to create an artificial reef for the proliferation of marine life. Additional wrecks include El Limón and Capitán Alsina, located about 30 meters (100 feet) deep, and the Don Quico at about 58 meters (190 feet) of depth. Nearby, an impressive system of karst rocks creates a meandering network of underwater caverns and tunnels over 100 meters (328 feet) long—an ideal place for technical diving. https://www.godominicanrepublic.com/poi/excursions/boca-chica/parque-nacional-submarino-la-caleta/
