It is located in the municipalities of Miranda do Douro, Mogadouro, Freixo de Espada à Cinta and Figueira de Castelo Rodrigo, spanning a lengthy area along the Douro River where it functions as the border between Portugal and Spain (hence "International Douro").

The park was created to protect the scenic landscape of the region, as well as its flora and fauna.

The Natural Park is characterized by its rugged and dramatic landscapes, featuring deep river valleys, steep cliffs, and rocky outcrops.

The park’s topography is the result of millions of years of erosion by the Douro River, creating a stunning and diverse natural environment.
