Because of the good accessibility and visibility, man was in the cave very early, possibly hunting for cave bears. Numerous excavations since 1926 have brought to light valuable findings (two fireplaces, stone tools, bone needle, a bone flute with two holes, medieval double-headed pendant, etc.). Other cave contents were fetched and used as fertilizer by farmers in the interwar period.
Only the first part of the cave is easily accessible. A horizontal passage can be followed for about 50 meters, sometimes upright, sometimes bent.
