Also known as Parque Nacional Juan Pérez Rancier, this remote park begins around 17km southeast of Constanza. Las Pirámides , a monument marking the geographic center of DR, is 46km away. The area records the coldest temperatures in the country, sometimes reaching -8°C during the night and, at 2438m, is the highest plain in the Caribbean. In theory, you can drive all the way to San José de Ocoa, around 90km to the south (though you might need a military vehicle).
