Designated a Unesco Biosphere reserve in 1977, the Sierra de Grazalema was declared the first natural park in Andalucia in 1984 and is one of Spain's most ecologically outstanding areas. The 51,695 ha park is famous for its spectacularly rugged limestone landscape of cliffs, gullies, caves and gorges.

The Cañón de las Buitreras is the strikingly named Gorge of the Vultures, after the colony of griffon vultures that nest in the area. The gorge itself is impressive, with often near-vertical sides at times reaching 200m high. In the bottom of the gorge is the Guadiaro river, which has eroded the limestone rock.

Sandwiched between the Alcornocales natural park and Sierra de Grazalema natural park in the far western reaches of Malaga province is the pueblo blanco (white town) of Cortes de la Frontera. It is in a superb vantage point overlooking the sweeping Guadiaro valley below, with a spectacular backdrop of the Serranía de Ronda mountains.
