It is the largest terrestrial-maritime reserve in the European Western Mediterranean Sea, covering 460 km² including the town of Carboneras, the mountain range of Sierra de Cabo de Gata, and 120 km² of the sea as a part of a Marine reserve.
It is of volcanic origin and is centred around the Cabo de Gata headland. Its climate is semi arid to the extent of being the driest location in Europe.
In 2001 it was included among the Specially Protected Areas of Mediterranean Importance.
In 2010 it was proposed as a dump for nuclear waste.
