Bears' Cave (Romanian: Peștera Urșilor, Hungarian: Medve-barlang) is located in the western Apuseni Mountains, on the outskirts of Chișcău village, Bihor County, northwestern Romania.

The cave remained closed until 17 September 1975, when the underground void was artificially opened by dynamiting the entrance during the limestone (marble) quarrying works.

Traian Curta, a miner from Chișcău, went down the shaft for the first time.

On the basis of complex studies carried out by the Institute of Speleology "Emil Racoviță" in collaboration with the Criș Country Museum in Oradea, the solutions for the layout and specific protection measures were established.

After 5 years of development, the cave was opened to visitors on 14 July 1980.
