8 kilometers from Baena, in the area known as ‘Puente de la Maturra’, is what is considered the fourth largest cave in Spain and the first at the provincial level. The formation, with rocks dating back to the Miocene and even older periods, presents as one of its main characteristics, a level of massive gypsum about 60 meters thick, stratigraphically located between two levels of impermeable rocks (marl) that prevent hydrological connections to other nearby gypsum strata.
With high-rise spaces in which up to four main galleries and two secondary galleries can be distinguished, it is developed on two different levels. The one with the best access is conditioned for your visit, with several lakes and gypsum crystal formations of great interest and beauty inside it. For its part, the second of them, being less accessible, has made it possible to conserve an important colony of bats in danger of extinction and various species of decapod crustaceans that develop only in this cave, as various studies have confirmed. international.
The cavity maintains a stable temperature throughout the year, about 21 degrees centigrade, which produces a pleasant thermal sensation and favors the visit in a journey of just under an hour through the very bowels of the earth.
