The Škocjan caves have been under UNESCO protection since 1986. This cave system consists of underground tunnels, subsoil runoffs, lakes, swallow holes, cave halls, subterranean gorges and other interesting features. The formation of the caves took place in the original Karst area, the area where karstic phenomena got their name from. It is one of the most tourist attractive caves in Slovenia.
