Sierra de San Pedro
The Sierra de San Pedro is a range of low hills that stretches for over 60 km in a NW/SE direction. It is parallel to the Serra de São Mamede to the west in nearby Portugal and is relatively lower than the latter. The range is located between the towns of Arroyo de la Luz north of the range and Alburquerque to the south, and the N-630 road in the east and the towns of Membrio and San Vicente de Alcántara in the west. The Peña del Águila Dam on river Zapatón that supplies water to Alburquerque is located in the range. A projection of the range stretching northwards from its western end is known as the Sierra de Carbajo, also named "Sierra de Santiago", a small range located between Carbajo and Santiago de Alcántara.
