Koper: Postojna Cave with Train Ride - group tour｜Slovenia

Explore the world-famous Postojna Cave, located in the Karst region, only a 50-minute drive from Koper. Enter the mysterious, more than 20 km long Karst cave system, with its great underground galleries and halls.

Admire magnificent cavernous halls with impressive sculptures and colors. Ride an electric train through the cave system and enjoy a guided walking tour. The visit of the cave lasts approximately an hour and a half. The temperature in the cave is around 10°C/50°F, so walking shoes and jackets are recommended.

Continue on for a beautiful short photo stop at Predjama Castle. Perched high up in the cliff, this castle dates back to the 16th century, but evidence indicates that this steep and imposing cliff has been fortified since at least the 13th century. Following your time at the castle, return back to Koper, where your tour concludes.
