In 1900 the cave was explored by the members of Speleological section Liburnia from Zadar; in 1903 a miner from Split, Luigi Minotto, informed a geologist, Fritz Kerner, about the discovery. Making a geological map of Dalmatia, Kerner visited the cave and published an article "Die Grotte von der Kotlenice am Nordfusse Mosor-planina."
Umberto Girometta had the most important role in promoting the beauties of the cave writing about it in magazines, newspapers and scientific publications which resulted in increased visits to the cave. In 1927 the Mountaineering Association Mosor founded a section for karst phenomenon research which main goal was to prepare the cave for tourist visits.
Girometta said about the cave that among so many caves that he explored in Dalmatia, this one had the most favourable living conditions; oriented towards noon, spacious, relatively dry, protected from the cold bura wind, a lot of light, a constant temperature of 16 ° C, the vicinity of water, forest and mountain. He also discovered a new species of cave spider, a rich cave flora; he also confirmed that the cave was inhabited in ancient times which was witnessed by the remains of crockery and bone fragments.
Due to the richness of stalactites and stalagmites this cave is among the most beautiful caves to visit in Dalmatia. The area around the cave is also very well arranged; benches and tables made of stone and wood, forest and clean nature.
