With over 110 kilometers of underground galleries, it is one of the largest and most complex cave systems in Spain. This natural site is notable for its geological formations and archaeological value, as well as housing the rock-hewn hermitage of San Bernabé, a place of worship carved into the rock that adds historical and cultural significance to the area.
