El Torcal de Antequera is a nature reserve in the Sierra del Torcal mountain range located south of the city of Antequera, in the province of Málaga off the A45 road in Andalusia, Spain. It is known for its unusual landforms, and is one of the most impressive karst landscapes in Europe.
The limestone nature of the terrain makes it especially susceptible to erosion by climatological agents such as rain and wind. It belongs to the Guadalhorce-El Torcal, area (13,616 hectares). In 1929, it was declared a Place of National Interest.
The Jurassic age limestone is about 150 million years old and was laid down in a marine corridor that extended from the Gulf of Cádiz to Alicante between the present Atlantic Ocean and Mediterranean Sea. These seabeds were uplifted to an elevation of over 1300 meters during the Tertiary era, resulting in a modest mountain range of flat-lying limestone, which is rare in Andalucia.

Later, a series of fractures, cracks and faults at right-angles were exploited by erosion and produced the alleys between large blocks of limestone visible today. The blocks themselves have been subjected to both dissolution by water (karstification) and freeze-thaw splitting action which, working on the limestone’s horizontal beds, resulted in the various shapes visible today, many of which resemble, and have been named after, everyday objects such as the Sphinx, the Jug, the Camel, the Screw, etc. Other flat surfaces have been karstified into rugged, rocky lands where travel on foot is difficult.
Due to its unusual limestone rock formations, Torcal de Antequera Natural Park (Parque Natural Torcal de Antequera) boasts an impressive landscape that is considered to be unique in the world. Its 1,171 hectares have often been used in science fiction films. It is easy to get lost while walking in its labyrinth of rocks, depressions and valleys, passages, landings and narrow passes.
Like many massive limestones, the Torcal includes caves and other underground forms, some of them of historical importance like the Cueva del Toro (Cave of the Bull) with its Neolithic artifacts. Their origins are also related to the dissolution of underground limestone by rainwater.
