Activity description:Interesting cave formed mainly by gypsum and clays with different rooms and cavities. A walking route through water steps and with some areas where you have to make small climbs and detours.
The cave presents slopes of 205 meters and a length of about 1300 meters, which makes it the deepest gypsum cavity in the world.
– Another interesting aspect of this cave is the presence of a colony of bats of great interest, although they are not always visible since they are one of the fastest flying species.
– We can observe how the water erosion effect has formed different cavities and curious rock formations, as well as  several surprises you will find especially in the final part.
