The caves were re-discovered in modern times on 12 January 1959 by five friends, who entered through a narrow sinkhole known as "La Mina". This forms one of the two natural entrances to the cave system. A third entrance was created in 1960 to allow easy access for tourists, just south of the Sierras of Tejeda, Almijara and Alhama Natural Park. The cave is divided into two main parts known as Nerja I and Nerja II. Nerja I includes the Show Galleries which are open to the public, with relatively easy access via a flight of stairs and concreted pathways to allow tourists to move about in the cavern without difficulty. Nerja II, which is not open to the public, comprises the Upper Gallery discovered in 1960 and the New Gallery discovered in 1969.
