Los Haitises National Park, National park in Hato Mayor Province, Dominican Republic.

Los Haitises lies in Hato Mayor and Samaná provinces and includes coastal waters, mangrove forests, and limestone karst formations spread over a wide stretch of land. The terrain shows cone-shaped hills, grottoes, and waterways that connect both coastal zones and forested interior areas.

In 1968, Law 244 created the Zona Vedada de Los Haitises, a forest reserve. Law 402 of 3 June 1976 turned it into a national park, and Decree 233 of 1996 expanded it from 208 to 826 km². Its boundary has been redrawn several times and remains uncertain.

The caves hold pictographs and petroglyphs made by peoples whose culture remains unidentified; some may predate the Taínos. "Haitises" comes from the Taíno word for highland or mountain range, though the hills stand only 30 to 40 m tall. Visitors reach the caves by boat with ecological guides from Sabana de la Mar.

Visitors usually travel by boat from small harbor towns into mangrove areas and to the caves, as large parts of the terrain are difficult to reach by land. Sturdy footwear and sun protection make outings easier when moving both on foot and by water.

Many bird species nest in the mangroves and on the forested hills, including species found only on Hispaniola. Early morning or at dusk the calls can be heard more clearly as flocks move through the trees.
