Valle Nuevo National Park, Mountain national park in La Vega Province, Dominican Republic.

Valle Nuevo National Park is a protected area of 910 square kilometers on a plateau above 2,200 meters in the Cordillera Central, mainly in La Vega Province. Its highest point is the 2,842-meter Alto de la Bandera, an extinct volcano. The park contains cloud forests, mountain plateaus, and grasslands, and its rivers feed the Nizao, Yaque del Sur, and Yuna watersheds.

Early Spanish chroniclers documented lakes in this highland region during the colonial period. The area later became a protected space to preserve the fragile mountain landscape.

The Cyclopean Pyramid, known as Las Pirámides, stands in the Valle de los Frailes beside Route 41 at a spot called La Nevera. It was built to commemorate the January 1959 inauguration of the Constanza–San José de Ocoa road and marks the former municipal boundary between the two towns. The monument has four segments.

Route 41, also known as Antonio Duvergé Road, runs directly through the park from north to south. You can reach the area in about two hours of driving from Santo Domingo.

In this Caribbean mountain region, temperatures at the highest elevations drop below freezing and can fall to minus 7 degrees Celsius. These extreme conditions create frost on the ground, which often surprises visitors expecting tropical warmth.
