The 0,5-1 million-year-old Budapest Cave is often called “Budapest’s underground flower garden”. This Budapest cave was discovered in 1930. After a long period of research and construction of visitor facilities the cave was opened to the public in 1986. The most beautiful parts of the cave can be observed during guided tours along the 300 metre long tourist path; these parts are characteristic of thermal karst formations. You can see walls covered with thick layers of mineral deposits that are unique in Europe: splendent, white crystals of gypsum, popcorn formations and calcite plates. The comfortable and safe walkways and modern lighting make the tour even more enjoyable.

Budapest is the capital of caves. It is the only capital in the world which has caves of significant size and length underneath its buildings and streets. More than two hundred caves are known under the Buda side of the town. However these caves also have a special place in the world because of their unusual thermal water based development.

The hydrothermal caves of Budapest were created by the same thermal springs that supply the famous spas of the capital and the entire area is on the tentative list of UNESCO World Heritage Sites.
