The Sierra de Cazorla, located in the east of the province of Jaén, gives its name to the Sierra de Cazorla, Segura y Las Villas Natural Park. Its 214,300 hectares make it the largest protected area in Spain.
It was declared as Biosphere Reserve by the UNESCO, forming a huge natural territory that stretches to the nearby Natural Parks of Sierra de Castril (Granada) and Calares del Río Mundo y de la Sima (Albacete).
The sierra de Cazorla is formed by a rough sequence of mid-altitude sierras that have their highest heights in the 2,107 meters of the hill of Las Empanadas or the peaks Cabañas and Yelmo, of 2,026 and 1,809 meters respectively.
The sierra de Cazorla has a rugged terrain with great drops, deep valleys, high walls and lush forests. Rivers such as Guadalquivir, Segura, Madera, Tus and Borosa begin to flow within this area.
