Voska luknja is a cave on the north slope of the Ivanščica massif. It is a diagonal cave, so its horizontal length of 25 metres (82 ft) is much smaller than its total passage length of 40.7 metres (134 ft). As mapped, it is the second deepest cave on Ivanščica behind Hanžekova jama at 22 metres (72 ft), but its total vertical difference is the largest in Zagorje, with potential for further expansion It is difficult to explore because of its narrowness and the entrance is difficult to access, but a tourist path has been planned.
