The cave is near the village of Shiroka Luka. It is over 1,400 m in length and is the fifth deepest cave in Bulgaria. An underground river flows through the cave bottom. For millions of years, underground forces have created wonderful cave formations. In order to reach the bottom, one has to pass 46 waterfalls. The name of the cave (Icy Cave) is related to an interesting natural phenomenon: in the summer, due to the circulating air, a huge ice stalactone grows in the first cave hall.
The cave has not been adapted for tourists and it can be visited only with a special equipment and experienced guides!
