The cave was discovered by miner Traian Curta in 1975 when he broke through an air vent during quarry operations.
It is named after the hundreds of cave bears that became trapped inside after a rockfall blocked the entrance.
The cave temperature remains constant at approximately 10 degrees Celsius year-round.
Archaeological analysis indicates the bears died primarily of starvation and age rather than hunting.
The 'Bones Gallery' is the most famous segment of the cave, containing articulated skeletons of Ursus spelaeus in their original deposition sites.
The cave is 1,500 meters long, though only a 521-meter portion is accessible to the general public.
A specialized ventilation system was installed to maintain the cave's natural microclimate and prevent algae growth caused by artificial lighting.
The Bears' Cave (Peștera Urșilor) is a limestone cave situated in the Apuseni Mountains of Romania, notable for housing one of the largest concentrations of cave bear (Ursus spelaeus) fossils in Europe. The cave spans three levels, with the upper level featuring the primary tourist route and significant paleontological displays. Discovered accidentally in 1975 during marble quarry blasting, the site retains its original geological formations, including diverse stalactites and stalagmites. The fossilized remains of over 140 cave bears were discovered inside, preserved after the cave entrance was sealed by a rockfall approximately 15,000 years ago. The facility is managed as a protected scientific reserve, requiring visitors to remain on designated paths to protect the fragile subterranean environment. Scientific research continues at the site, which remains a key location for studying Pleistocene-era fauna in the Carpathian region.
The entrance area of the cave and the surrounding forested valley outside offer the best natural lighting for photography.
Bring a light sweater or jacket, as the cave temperature is constant and chilly regardless of outside weather.
Wear sturdy, non-slip walking shoes to navigate damp, uneven limestone paths.
Plan to arrive early to avoid long queues during summer weekends and public holidays.
Attempting to touch the cave formations or wandering off the guided path; these actions degrade the ecosystem and are strictly monitored.
Closed on Mondays; open Tuesday through Sunday.
Photography inside the cave is strictly prohibited; touching the cave walls or formations is forbidden to prevent damage.
