Kőkapu, Natural limestone cave in Budapest, Hungary.
Kőkapu is a natural limestone cave in Budapest with distinct rock formations created by thermal water activity over geological time. The cave forms part of the extensive underground network of passages and caverns that lies beneath the city.
The cave developed over millions of years through the interaction of thermal springs with limestone bedrock beneath Budapest. This slow geological process shaped the formations visible to visitors today.
The cave draws the interest of local speleological societies who conduct regular research expeditions to document its geological features. This ongoing study has established the site as an important location for understanding Budapest's underground geology.
Access to the cave is regulated for safety reasons and requires coordination with authorized guides and obtaining necessary permits beforehand. Visitors should plan ahead since exploring the site requires special precautions and arrangements.
The entrance resembles a natural stone archway that gave the cave its name Kőkapu, which translates to Stone Gate. This distinctive feature makes the entrance easily recognizable when approaching the site.
