Postojna Cave  (Postojnska Jama)

Postojna cave is one of the most important and iconic destinations in Slovenia. Just one simple fact: it got electric lights inside 10 years before Ljubljana, modern day capital of the country. The cave is opened for visitors for more than two hundred years and boasts the first underground cave railway in the world. It is also known as the "Queen of Caves" and that is, certainly, for reason.

By the way, don't let all this fact to fool you and make you think that it's a kind of "disneyland experience", because it's nothing like that: the cave is incredibly opulent and colourful, it's a true natural wonder.

Slovenia can be named the world's capital of caves. Yes, there are bigger and longer caves than here, but it's the first area where the caves were explored and opened for visitors. Among 5000 of Slovenian caves two are the most known: Postojna cave and Škocjan cave. It's very difficult, almost impossible, to say which one of them is more interesting and impressive, so different they are. But Postojna cave (Postojnska jama) is certainly the most known and visited.

At the moment we know about 25 km of underground labyrinths, but the cave is longer it is connected to others and it's just a matter of time to find and explore new passages.
