Los Haitises National Park is a national park located on the remote northeast coast of the Dominican Republic that was established in 1976. It consists of a limestone karst plateau with conical hills, sinkholes and caverns, and there is a large area of mangrove forest on the coast. Other parts of the park are clad in subtropical humid forest and the area has an annual precipitation of about 2,000 mm (79 in). The park contains a number of different habitats and consequently has a great diversity of mammals and birds, including some rare species endemic to the island. Some of the caverns contain pictograms and petroglyphs. The park has become a popular ecotourism destination but the number of tourists allowed to visit is limited.
