The region is made up of the municipalities of Alfândega da Fé, Carrazeda de Ansiães, Macedo de Cavaleiros, Mirandela and Vila Flor. It is characterized by a climate with very hot, dry and prolonged summers and cold winters dominated by frost.

It extends to the valley of the Douro River, in the company of the tributary river Tua, and the Tua Railway Line, practically deactivated in its entirety.

It stands out the Geopark Land of Knights that, geographically, is coincident with the area of ??the county of Macedo de Cavaleiros. It has an important geological and biodiversity heritage, as well as a historical-cultural heritage, regional products and gastronomy, which keeps alive the identity of the people.
