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 village of Benoajan is rightly famed for the caves which are well signposted around the area. South of the village of Benoaján heading towards Cortes de la Frontera, a side road leads off on the right, serving as a carpark.

The entrance of this cave can be seen from the railway as it heads north from Benaoján station two kilometres away. It's called the cat cave as its entrance is said to look like a cat's head.

As the name suggests (the prefix Ben- found across the region derives from the Arabic 'ibn', 'son of'), this is another village of Moorish origins. Located very near to Montejaque, the settlement can be found in two halves. The original village was built on a mountainside with the lower community in the Guadiaro river valley that grew up around the railway station.
