Vjetrenica (which means “wind cave”) is the largest cave in Bosnia and Herzegovina. In the warmer parts of the year a cold air blows from its entrance. The cave has been explored and described to a total of about 6,1 thousand meters in length. There are several permanent and occasional streams and lakes, many stalactites, flowstone, draperies, cascades and others forms.
There are a lot of different boilogical species and with that is one of the richest caves in the world. On the rocks at the entrance to the cave there are two carved stones, typical for medieval tombstones in this region.
