The 20,570 metre-long Postojna Cave system is the longest cave system in Slovenia as well as one of its top tourist attractions, visited by over 500,000 visitors per year. The 5.3 kilometre-long trail is opened to the public which makes Postojna Cave the longest publicly-accessible depth of any cave system in the world. Its Grand Hall can receive up to 10,000 visitors and often serves as a concert venue.

The caves are also home to the endemic olm (proteus anguinus), the largest trogloditic amphibian in the world. Part of the tour through the caves includes a pool with some olms in it, making this one of the rare places in the world where the olm can be seen by tourists.
