Also known as "the witches' cave", this impressive complex of caves and galleries will surprise you. The main cavity was eroded by a strong current of water known as the Regata del Infierno. In its widest area, the cave has a length of 120 m, by about 22 to 26 m and an average height of 10 m. The set is completed with two higher galleries, an impressive place of immense dimensions!
