Cave has two entrances. First is in the wall right above spring Hubelj. It was formed by lesion and brings us through very narrow slots to Hall of quarrels. Second entrance was artificially extended and is on eastern end of Hall of quarrels. This is triangular opening with each side of 40 centimeters. The Hall of quarrels is somewhere wider than 6 meters and just as high. The floor and the ceiling are overlapped by white stalactites, which are dry and on the is loading a thin layer of preperline. Hall of quarrels has direction east-west. On eastern end of tunnel turns sharply towards notrh. Parts of the cave from here are at high water level inaccessible. Also character of the cave changes. Tunnels becom narrow splits, from 0,5 – 2 meters wide and several meters high. On the bottom of the tunnel usually flows the water. Up the tunnel we come do siphon Lake. West from the lake the tunnes rises and than splits into several parallel splits in direction north-south, where they end. After 3 meters long siphon opens small space in which at stong drought flows small stream. The cave continues also here. Interesting is that the water never floods the entire Hall of drafts. As well as never flows through dug entrance.
