Parque Natural da Serra de São Mamede

In the flat Alentejo, the idea of ​​a mountain range is like the idea of ​​an oasis in a desert. Well, the Serra de São Mamede Natural Park represents exactly that. From Castelo de Vide to the southeast stretches this magnificent mountain range, the highest south of the Tagus, headed by the Serra de São Mamede (1,025 meters maximum altitude). The Serra de Castelo de Vide (762 meters), the Serra Fria (953 meters), and the Serra do Marvão (867 meters) fill the remaining part of the Natural Park. Morphologically, the park is composed of a layer of granite on the outside and schist, greywacke, limestone, and quartzite at its core. In fact, it is the latter that are most surprising, with the quartzite rock ridges forming strange aligned reliefs, as if they were ruined walls.
