JCFG suggests that there is some doubt as to whether the river is the Clarin or Clarion.

This cave is a resurgence for some of the water that sinks on the Muela range. The entrance contains a still pool in the summer, the active resurgence being in the streambed to the south. In winter the cave is very forthcoming.

A 12m sump at the entrance leads to a 20m section of canal and the second sump of 2m. Scaling poles are then necessary to reach a number of different levels. The cave ends at two deep sumps.

During at least 1993 and 1994, the Grupo de Exploraciones Subterraneas de Estepona have been diving this site and possibly Peter Plummet (239). A poor quality video has been made; the site has been surveyed to 362m. The spring apparently has the bracketed name above.

The site has been re-explored and re-surveyed by Spaniards. See FCE BCE no 14 pp5-8 Santander 2000. A recent survey by Spanish groups reflects what was found and surveyed in 1975. In October 1995 the site was dived and re-explored by British divers.
