Notranjska Regional Park embraces one of the most beautiful tourist caves in Slovenia-the Križna jama cave with emerald lakes, connected by an underground crystal-clear river.
Ancient bones of cave bears can be seen inside passages and by the number of specialised cave dwellers, the Križna jama cave ranks among the richest in the world.
Križna jama is the third longest cave system in Slovenia. People have been visiting the caves ever since the Neolithic Era, but before that, its master was the now extinct cave bear.
The magical attraction of the Križna Jama cave hides in its little lakes. The underground lakes, that are up to 6 metres deep, were formed behind sinter barriers, which emerged because calcareous sinter deposits faster on rapids than in slow waters.
Walking along the paths used by cave bears for thousands of years and paddling along the lakes in the karst underground, is an experience you won’t forget.
