Close to the Haitian border on the Dominican Republic’s northwestern coast, this white-sand beach, which is part of Montecristi National Park, sits below an 800-foot-high limestone mesa. Hike a rough stretch through rocks to the beach and you’ll find clear water but strong currents—these waves are not for children, and even excellent swimmers should be very cautious. Shipwrecks from the colonial days draw experienced divers to nearby Isla Cabrita, while empty sands attract Dominican families on weekends. Playa El Morro is almost completely off the tourist radar and all but deserted on weekdays.
