Bijambare is a protected landscape located in the Dinaric Alps, characterized by a complex of eight karst caves. The Central Cave, measuring 420 meters in length, is the only one fully accessible to the public and features significant stalactite and stalagmite formations. The reserve encompasses 497 hectares of coniferous forest, primarily consisting of fir, spruce, and pine trees. Visitors traverse the forest via a dedicated path that leads from the entrance to the cave complex. The area serves as a habitat for various protected species, including bats, which inhabit the cave systems. A miniature tourist train provides transport from the entrance area to the vicinity of the caves. The site includes designated zones for educational programs, recreation, and ecological monitoring. The karst terrain is shaped by the Bebrašnica river, which sinks into the subterranean layers near the caves.
