Geography
This arid-looking series of parallel ranges is cut by many ravines. It is located north of Castellote, at the eastern end of the Iberian System, roughly between Molinos and Berge. There are many fossils from the Jurassic and Cretaceous periods in this area.

The Ermita de la Virgen de la Peña near Berge, is in the northern side of the Sierra de Caballos. El Picuezo is an original rock formation near Molinos. The impressive Grutas de Cristal "glass caves" are located in the area of these mountains, within Molinos municipal term.

There are other mountain ranges with the name "Sierra de Caballos" in the world. One of them is in Isla de Pinos, Cuba.
