These extraordinary geological formations offer a journey to a fantasy world consisting of 500 m on four levels with an average height of 6 m per level. To enter the caves you have to descend about 300 m holding on to a rope railing.

It has artificial lighting so that you can fully contemplate the whimsical figures of stalactites and stalagmites that have been created by the action of time. These formations receive names such as: "chimneys", "the boyfriends", "castles", "thrones", "monsters"; others have remarkable sonority and hence their names: "harp", "timpani", "piano", "strings and brass". 

 The caves are quite deep, so they can only be explored in the company of an expert guide.
