Description

Pozo Azul (Blue Pot) is a deep blue karst spring, as the name suggests. It is much visited by tourists. The cave behind the spring is filled with water and only accessible to cave divers.

The water of the spring emerges from a huge cave, starting with a 700m sump. After a 300m swim, a cascade, and a short stream passage a second sump is reached. This second sump is known for 2,220m and a depth of -70m and is the longest sump in Spain.
