Geography of the Sierra de Cazorla, Segura & Las Villas Natural Park
The Sierras de Cazorla, Segura y Las Villas Natural Park stretches along the whole of the eastern border of the province of Jaen.
The surface of the area is characteristically mountainous, although the ranges making up the Natural Park vary greatly and are divided by deep valleys carved by water erosion, and have high cliff faces. Its craggy reliefs are most typical of the southern area of the Natural Park, since the centre and north are gentler. The height of the terrain tends to decrease from north to south.
The Sierra de Cazorla is the most south westerly section of the Natural Park, whose highest peak is Gilillo (1,847 m). It is a divisor line between the vast olive tree groves and the mountainous area of Jaen. Its easterly face drains practically all of its water into the Guadalquivir. To the north is the Sierra de las Villas, the least known range within the Natural Park, and borders with the province of Andalusia. It has more depth than Sierra de Cazorla, with steeper slopes and uninhabited areas covered with dense forests. The highest peak here is Blanquillo (1,830m).
The Sierra de Segura covers the centre and north to northwest of the Natural Park, and is by far the largest of the three ranges making up this protected space, occupying some 68% of its total surface. Its highest point is Pico Banderillas, measuring some 1,993 metres.
