The Sierra de Gredos, in the extreme south of Castile and León, is the consequence of the erosion caused by the distant eras of glaciation, reaching our days a spectacular landscape of shapes and colors, of glacial lagoons, cirques, cliffs and gorges.

Biologically it is one of the most interesting natural spaces in Western Europe, because in addition to the great variety of species perfectly adapted to the changing climatic and altitude conditions, the Sierra de Gredos is very rich in both animal and plant endemisms.

Being a transitional territory, a border that separates the northern and southern plateaus, it has been a place of passage for many peoples for centuries, which has left an interesting heritage compendium that covers thousands of years of history.
