Caves of Aggtelek Karst and Slovak Karst (Hungary, Slovakia)
Caves of Aggtelek Karst and Slovak Karst The variety of formations and the fact that they are concentrated in a restricted area means that the 712 caves currently identified make up a typical temperate-zone karstic system. Because they display an extremely rare combination of tropical and glacial climatic effects, they make it possible to study geological history over tens of millions of years.
