Öreg-kői No. 2. Pothole

Öreg-kői No. 2 Pothole is a vertical cave system located within the limestone formations of the Gerecse Mountains near Bajót. The formation features a network of deep shafts and narrow passages that extend through the rock.

The cave system formed over millions of years through water erosion of the local limestone bedrock. This geological process created the distinctive vertical shafts and passage networks that define it today.

Hungarian speleologists regularly document and study this cave system, contributing to the understanding of karst formations in Central Europe.

Access requires specialized cave exploration equipment and extensive technical expertise for this type of terrain. It is advisable to contact local authorities and bring experienced guides to ensure safety standards are met.

The cave maintains a constant temperature of around 10 degrees Celsius throughout the year. These stable conditions make it an important hibernation site for several bat species that seek refuge there.
