The Cañón de las Buitreras Natural Monument is located on the periphery of Los Alcornocales Natural Park. Declared a natural monument in 2003 and covering an area of 218,766 square meters, it is a canyon more than 100 meters deep, carved by the Guadiaro River.
The Guadiaro River has carved this narrow gorge into the limestone and marl-limestone that form the mountain ranges of Ronda and Grazalema. The river's erosive force, combined with high rainfall, has sculpted twisted passages and incredible cavities typical of karst landscapes. The presence of certain drops in the river, creating numerous impressive waterfalls, further enhances the beauty of the surroundings.
The local flora includes an holm oak forest interspersed with junipers, mastic trees, and carob trees, but the dwarf palm stands out as the only European palm, with strikingly tall specimens. The fauna consists of the animal that gives it its name, a colony of griffon vultures, and other birds such as stock doves, rock doves, and the white-throated dipper, in addition to the otters that inhabit the waters of the Guadiaro River. The landscape is complemented by human constructions like tunnels for trains and the Puente de los Alemanes (German Bridge), which rises 60 meters above the bottom of the ravine.
