POSTOJNA CAVE is the only karst cave with a railway, which was built more than 140 years ago. The unique tourist train will take you to the underground network of karst corridors, galleries and halls. During an hour-and-a-half-long guided tour, you will learn about all of the most important karst features: the largest, 16-metre-high stalagmite known as the Skyscraper, the crystal white symbol of Postojna Cave – the Brilliant, the oldest underground post office in the world and the most famous underground animal – the olm or the human fish.
