On the 17th of september 1975, when the marble quarry at Chişcău was blown up, a break formed in the massif. After scientific researches, a part of the cave was cleared and electrified, and opened for tourists on the 14th of July 1980. Bears Cave is not large, but has many relevant cave structures, which makes it unique. It measures 1.5 km, 521 m being declared a scientific reservation. There are three galleries: the Bear Gallery, Emil Racoviţă Gallery, and Candle Gallery, as well as four halls: Candle Hall, Spaghetti Hall, Emil Racoviţă hall and Bone Hall. There are also many fossil remains of the cave bear - Ursus Spelaeus - extinct about 15,000 years ago.
