The karst cavern systems of Aggtelek

The geographically connected Aggtelek and Slovakian karst consists of 1200 known caves, 280 of which are open on the Hungarian side. Aggtelek and Slovakian are one of the Most Beautiful Caves in Hungary. These caves formed approximately 2 million years ago within the 220–240 million-year-old Middle Triassic limestone. The majority of the formations were formed by the action of flowing water on the limestone, which acted as a solvent and abrasive. Many people believe that some of these caves were even known and discovered by ancient humans.

The Aggtelek National Park is located in the Gömör-Torna Karst region, which is rich in natural and cultural resources. It is Hungary's first national park dedicated to the preservation of abiotic values, superficial land formations, and caves. The caves of the Aggtelek Karst and the Slovak Karst were inscribed on the UNESCO World Heritage List in 1995. This UNESCO World Heritage site is made up of seven parts. In Hungary, they are Aggtelek, Szendr-Rudabánya Hill, and Esztramos Hill, and in Slovakia, they are Dobiná Ice Cave, Koniar plateau, Pleivec plateau, and the Silica and Jasov neighborhood.
