The drainage of the region under which the caverns lie is mostly underground.
No less remarkable are the Okno, Vodi and Demenyfalva caverns in the county of Lipt6, the Veterani in the Banat and the ice cave at Dobsina in Gomor county.
None of them is of any importance except Cabrera, which is full of caverns, and was formerly used as a place of banishment.
Thus the scenery of a limestone country depends on the solubility and permeability of the rocks, leading to the typical Karst-formations of caverns, swallowholes and underground stream courses, with the contingent phenomena of dry valleys and natural bridges.
In the neighbourhood are the cave of Drach, containing several underground lakes, and the caves of Arta, one of the largest and finest groups of stalactite caverns in western Europe.
