The river Riaza has excavated the hard limestone of the Segovian plains to create one of the largest collections of gorges, canyons, cliffs and ravines in the Iberian Peninsula.

In addition to its spectacular landscape, this isolated geographical region is the home of an important concentration of birds of prey, most notably 200 pairs of Griffon vultures. The hillsides and rocky escarpments are covered with woods of incense junipers, a real living fossil of the Tertiary epoch. In an opening of the canyon, one can visit the solitary Romanesque remains of the convent of El Casuar.

This natural space holds the European Charter for Sustainable Tourism granted by the EUROPARC Federation (an umbrella organisation for Europe’s protected natural spaces) for various reasons, including its outstanding initiatives aimed at promoting the rural environment and effective management and visitor control systems.
