With 1381 meters of maximum altitude reached at Pico do Talegre, the Montemuro Mountain is the eighth highest elevation of Portugal, located between the Douro River to the north and the Paiva River to the south. This mountain, with a steep relief on almost all sides, has populated villages scattered throughout the hills near water courses, as for instance near Bestança River, which divides the mountain in its south-north direction, up to an altitude of 1,100 meters. 

A Site of Community Importance (SIC) of the Rede Natura 2000, the Montemuro Mountain has a biodiversity of high importance, thanks to its habitats in good state of conservation (some of which of considerable conservation value, such as the peatlands) and to the broad community of vertebrates, that integrates innumerable species with the threat status as, for example, the Iberian Wolf (Canis lupus). The Ardena, Balsemão, Cabrum, and Bestança Rivers as well as Ribeiro do Corvo are born at Montemuro Mountain.
