This cave, with an openning near the tourist route leading up to the Giewont peak, is located not far from the Kalatówki shelter. Depending on the water level, the combined length of Dudnica's sumps reaches around 50 m (app. 164 ft). However, the dry passages between the sumps make diving here slightly difficult. A huge advantage of the cave is the small, just a few-metre-long distance between the first sump and the cave opening, which means the tedious equipment transportation can be avoided. Dudnica is connected hydrologically with Jaskinia Bystrej (Bystra's Cave), but the passage is too tight to be crossed by a human.
