The caves are spectacular and well displayed, with countless stalagmite and stalactite formations – never two the same.
The cave system is really extensive and you only cover a fraction but there is so much to see, and all quite incredible and lit well enough even for photos to be taken. It’s a truly stunning natural attraction, a must see if you are visiting Slovenia. Just don’t forget to bring a jacket as it is cold down there! The cave is located on the northern edge of the town of Postojna in southwestern Slovenia, some 50 kilometres (31 miles) southwest of Slovenia’s capital Ljubljana.
