Áfonya utcai Cave, Natural cave in District II, Budapest, Hungary
The Áfonya utcai Cave is a natural cave beneath Budapest's streets, featuring interconnected passages and chambers carved by hot spring water. The underground system extends across multiple levels, forming a complex network that sits hidden beneath the city above.
The cave formed over millions of years as hot thermal springs continuously dissolved limestone beneath the city. These geological processes created an extensive underground structure that remains active beneath Budapest today.
The cave belongs to a network of over 200 subterranean formations in Budapest, making this capital city a center for geological research and exploration.
Access to the cave requires specialized equipment and participation in guided tours, with strict safety and environmental protocols in place. Visitors should be prepared with sturdy footwear and good physical condition for underground exploration.
The cave is part of a network of over 200 subterranean voids that honeycomb beneath Budapest's surface. This makes the city an unusual place for geological research and underground exploration worldwide.
