The only karst cave in the Geopark area that is open to the public all year round. The cave is 50 metres long, of which a small 20-metre section with a very characteristic entrance hole is open to the public. Both the cave and the cliff made of Devonian limestone among which it is located are protected as a natural monument. The curiosity of the cave is the remnant of a former mining shaft associated with lead and silver mining and unusual ice drips, which can be found in winter in the accessible corridor of the cave. The unusual name of the cave is connected with local legends about devils flying out of underground depths. The cave is situated on the north-western slope of the Żakowa Mountain, close to the localities of Skiby and Gałęzice. It can be reached, among others, via the blue tourist trail leading from Chęciny.
