Sierra Morena
In the southeast is the ridge of the Sierra Morena, the southern border of the Meseta Central and the region's border with Andalusia. Within the Sierra Morena, distinction can be made between the Sierra Madrona, Sierra de Alcudia and Sierra de San Andrés. At the other southern extreme of Castilla–La Mancha, the Sierra de Alcaraz and Sierra del Segura form part of the Sistema Bético.
