The dive
According to the Andalusian sump blog this is the most important submerged cave in Andalusia, and in 2012 it was one of Spain's four deepest sumps.
Profile and sections
According to the Andalusian sump blog this is the most important submerged cave in Andalusia, and in 2012 it was one of Spain's four deepest sumps. Málaga clubs (SEM, GESM, Mainake among others) have explored it since 1978–1980, later Grupo Gaia and AAES among others. Neolithic pottery was found in an air gallery. The average flow is ~725 l/s, but after winter rain it is a violent spring.
Practical: diving happens in summer. In June 2026 Yunquera town hall hosted the first international cave-diving meeting here, with sump dives in groups after registration.
