Fed by thermal waters filtered through the karst stone of the Bükk Mountains, this bathing complex is inside a natural cave and belongs to the larger Miskolctapolca spa resort.

There are seven indoor pools, including a hydro-massage pool, enclosed by the cave’s bare limestone walls and with naturally heated water at temperatures ranging between 29 and 35°C. In summer you can also use the outdoor pools, and there three for children to play in.
