Sierra de San Pedro

Sierra de San Pedro is a mountain range in the greater Montes de Toledo range, Spain. It is named after Saint Peter the apostle and rises in the limits of Cáceres and Badajoz Provinces, in the western part of the autonomous community of Extremadura close to its border with Portugal. This range gives its name to the Sierra de San Pedro - Los Baldíos comarca. This mountain range separates the drainage basin of the Tagus to the north from the basin of the Guadiana to the south. The main rivers that have their sources in this range are the Rivera de Aurela, flowing towards the Tagus, as well as the Zapatón River, a tributary of the Xévora River that flows through Portugal into the Guadiana. The Sierra de San Pedro is a Site of Community Importance in Spain with ID ES0000070.
