Las Sierras de Cazorla y Segura Biosphere Reserve

UNESCO Biosphere Reserve, inscribed 1983, in Spain. This biosphere reserve and natural park include the upper reaches of the Guadalquivir River, together with a vast reservoir built for hydroelectric power generation, and extensive mountains and forests. The landscape is a mosaic of peaks, valleys, rocky gorges and vertical cliffs, and displays many typical karst limestone features. The Sierras of Cazorla, Segura y las Villas are part of a great mountain massif. They are dominated by several peaks over 2,000 m, with Empanadas being the highest. The forests are particularly notable.
