This impressive environment has as a common denominator the Tajo River, in the stretch that forms the natural border between Spain and Portugal in the western part of Extremadura. The natural park extends over a total area of about 50,000 hectares.
The typical vegetation is the characteristic Mediterranean mountain of holm oaks and cork oaks, with extensions of brooms and various species of rockroses. The orography of the terrain with its rocks and canyon walls, vegetation and watercourses give rise to very attractive landscapes that contrast with the surrounding plains.
A privileged destination to practice bird watching, as well as large mammals such as deer or wild boar. We can also find otters and numerous smaller mammals. In the park there are several natural refuges where important bat populations are located. Other notable species are the green lizard or the European giant tortoise.
In addition to the beauty of its landscapes and the ornithological richness of the park, another of its attractions is the cultural heritage with one of the most important megalithic ensembles in Europe.
