The huge cave system, officially known as the Gömör-Torna karst, has been a UNESCO World Heritage Site since 1995. There are a total of 712 caves in an area of more than 20,000 hectares that also extends over to Slovakia, of which 273 are found on the Hungarian side. The largest and most famous cave is the Baradla-Domica cave system. The Hungarian part, Baradla is 25, while the Slovak Domica is 5.6 km long. It is also the most visited cave in this area, where you can choose from plenty of organised cave tours according to your interests and stamina. One, two or even seven-hour cave tours depart from the entrance of Aggtelek and Jósvafő. The shorter ones lead along the paved, illuminated routes, through exciting halls full of stalactite formations, such as the Giants’ Hall or the Concert Hall, where musical concerts are held regularly. Longer tours, however, allow you to explore the less developed parts of the cave, guided by an expert, of course.
