The cave is disposed on the left (SW) bank of the river at NW slope of the hill. The main direction of development is NS. It has two entrances - lower disposed at altitude 2091m. and upper whish is higher. The lower one is 1.2 m wide and 1 m high. Little vertical passage leads to a crossing of two horizontal galleries. The first one with running river (discharge ~ 5 l/sec) and the second one is dry. The upstream passage is 25 m long with average dimensions 2 m wide and 2.2 m high. Then the gallery branch it two passages as Y. The river is coming from the sump on the end of the left one. Downstream the river flows few meters and hides in a fissure. The first part of the dry passage is 30 long – the profile of the gallery is semi ellipsoid with average dimensions ~ 1.30 m wide and 1.50 m high. This leads to little room, where is the second crossing. The left branch goes 49 m in N-NE. The bottom is covered by clay. The walls and selling are covered of stalactites, stalagmites and flowstone concretions. In the north direction from the room leads low, oven-shaped and covered with clay passage (length 18 m). Further the gallery became high and finished in the foot of a vertical wall – 9 m high. After climbing, descending and some more meters of walking the cavers reach the room just before the second (upper) entrance of the cave (0.75 m wide; 2 m high).
