Secret world beneath Hungarian capital —
A maze of cavern networks lurks beneath the hills of Budapest. Many caves are open to the public for tours or guided spelunking adventures.

Mattyas Hill caves —
The longest cave system in Hungary is located under the Mattyas Hill. A small part of the complex is open to adventurous tourists and geologists training to explore more inaccessible caverns.

Gellert Hill cave —
In the 1920s, the Gellert Hill cave was used by a group of Pauline monks who built an entrance inspired by similar rock constructions in Lourdes, France. It was a chapel and a monastery between 1926 and 1951.
