Caving around the Costa del Sol is a good option for discovering surprising corners. The caves in Málaga province give you the chance to explore life in the depths of the earth and enjoy contact with water, as many of them hide lakes and aquatic formations.
The Hundidero-Gato system in Benaoján, more commonly known as the Cueva del Gato, is one of the recommended caving options. It has a permanent source of flowing water, chasms, lakes, siphons and canyons for enjoying subterranean contact to the maximum.
The Cueva del Agua in Archidona, the Cueva de la Tinaja in Tolox and the Cueva de las Excéntricas in Igualeja are just some options worthwhile exploring.
