Stepping stones in a cave
For 140 years, the Postojna Cave, as the only cave in the world, offers a unique and adventurous ride with a special train, which will take you into the cave, under spectacular underground arches, which are embellished with chandellier look-alike stalactites, through a beautiful subterranean world full of playful limestone sculptures.
From 300 metres of accessible routes in 1818, a visitor today can enjoy the tour of 5 km through  tunnels and passages which takes about an hour and a half. The tour begins at the entrance platform of this unique cave railway, where particularly in the summer you can feel a lively bustle otherwise  typical of the biggest train stations in the world. This is where 3.7 km long railway tracks begin.
