ATTRACTIONS OF THE VISIT
Observation of the relief: Vertical strata of Armorican quartzite, the Santa Lucía syncline, the Trujillo peneplain, strike-slip faults, the narrow anticline of the sierra, etc.
Observation of raptors: The quartzite outcrops provide birds of prey with safe nesting places in the form of narrow ledges from which they fall into the void in search of a thermal to lift them: griffon vultures, eagles, Egyptian vultures, kestrels, and other raptors frequent these inaccessible crests.
Observation of archaeological remains: The particular geographical circumstances of this sierra have encouraged the development of human communities since antiquity, as is shown by the wealth of remains left by the ancient inhabitants of the area. On the path up to the summit the remains of the walls of a medieval settlement can be seen, and on the top a watch-tower built of stone and mortar.
This sierra also contains various sets of schematic cave paintings from the prehistoric period known as the Chalcolithic. Representations of human figures (ancoriformes) can be distinguished and also dots and parallel traces (tectiformes) in ochre tones arranged on the smooth surfaces of the quartzite strata facing the west.
