Los Haitises National Park is a national park located on the remote northeast coast of the Dominican Republic. It is a protected virgin forest with little road access. The number of tourists allowed is limited, but since 2000 it has been a relatively popular destination for ecotourism. Haitis (singular) means highland or mountain range in the Taíno language, although the elevation of the park's hills ranges from 30–40 m (98–130 ft). There is a multitude of caverns created by water erosion. Native Americans adorned these caverns with pictographs and petroglyphs. The culture or cultures which created these artworks remain unidentified, some of them possibly predating the Tainos.
The park was created by Law 409 enacted June 3, 1976. It was preceded by a Reserva Forestal (Forest Reserve) called Zona Vedada de Los Haitises (Los Haitises Prohibited Zone), created by Law 244. In 1996, it area was expanded from 208 to 826 km2 (80 to 319 sq mi) by Decree 233. Its boundary, which has been redrawn on multiple occasions, is presently uncertain. The bulk of the park is located in the municipality of Sabana de la Mar, province of Hato Mayor, while the remainder lies in the provinces of Monte Plata and Samaná. Sabana de la Mar is the site of a visitors' center.
Despite advanced deforestation, the precipitation is still considerable, ranging from 1,900–2,000 mm (75–79 in) annually. The park is near the top rank in both annual total rainfall and annual number of rainy days among sites in the Dominican Republic.
