The underworld was created slowly, in millions of years. You will hop on a little electric train and drive thru the kingdom of stalactites and stalagmites and then take a short walk to see the unique and quiet resident. There lives a human fish, in complete darkness. The perfect time to visit Postojna is summer, since inside is the same temperature all year round, only 8°C. This is half day excursion.
