Krásnohorská Cave

Krásnohorská Cave is a karst cave situated at the northern foot of the Silická planina Plain, in the Slovak Karst, 6.5 km southeast of Rožňava, in Slovakia. With unique natural decorations of bizarre shapes and unusual structure composed almost entirely of calcium, it is currently listed by the Guinness Book of Records as the cave containing the largest stalagmite in existence, generally accepted as being about 12 metres in diameter and 32.7 metres in height. It grows significantly in volume every year as the incessant drips solidify.

The length of the cave is 1,350 metres to 1,450 metres and it represents the end of the cave system underground stream Buzgó.
