The visitor’s curiosity is satisfied by facts about the formation of caves, a guided visit through passages and chambers and, above all, by observing the stalactites hanging from the ceiling, the stalagmites growing up from the floor, the pillars formed when stalactites and stalagmites meet, the folds of calcite curtains and the other sequences of fantastic shapes and forms. 

The desire for knowledge has also prompted experts in karst phenomena and life in the karst to research the special geological features of the cave, the formation and development of speleothems (the generic term for calcite formations in caves), and the living creatures that are found in caves – both those that have strayed underground by chance and those that have adapted to life in eternal darkness.
