Below Budapest lies an extensive cave system of about 30 kilometres in length. These caves are the sources of hot water for the baths. The caves have also served as wine cellars and shelters.
The Pál-völgyi cave is Budapest's longest cave and was discovered during construction work in 1904. Like many other caves, the Pál-völgyi cave was formed by hot springs. The system of corridors is no less than 13 kilometres long, but visitors can only visit part of it. You can go 500 meters into the cave. Be prepared for some climbing, because there are quite some height differences. In the cave there are many stalactites that are formed by minerals that were carried away by the warm water. The applied lighting makes the look extra beautiful, enhanced by soft music.
The Szemlő-hegyi cave is not that big and this cave also has less height difference (but still about 50 meters). The air in this cave would be beneficial for people with a chronic condition. Are you looking for unique sights in Budapest? Then these caves should not be missed.
