A relatively newly discovered (1981) underground cave which has become the most important natural sight in the community of Luče apart from the Igla. It is considered to be one of the most beautiful highland caves in the Alps. The entrance to the cave is through a sinkhole and it was often hidden by large quantities of snow which did not melt even in the summer. The cave is over 1300 meters long with 800 meters open for visitors. A mountainous scenery, the entrance through a sinkhole, an ice lake and ice sculptures, a rich decor of stalagmites and stalactites - all these elements make a visit to the cave unforgettable.
