Postojna Cave

Postojna Cave is without doubt one of the most diverse cave systems in the world.

Its 24 kilometres of passages, galleries and magnificent halls offer a unique experience of the underground world.A fantastic web of tunnels, passages, galleries and halls, the astonishing diversity of Karst features as well as easy access are certainly the main reasons for such popularity of the cave and a large number of visitors, which has already reached 35 million in 200 years.The Postojna Cave train has been taking visitors around the cave for 140 years. Its 3.7-kilometre long journey begins at the train-boarding platform of the unique cave railway, where – especially in the summer – a lot of hustle and bustle is present, the kind that is otherwise typical of the world's largest railway stations. In 1818, just over 300 metres were accessible, whereas today visitors get to enjoy more than 5 kilometres of show cave passages during regular cave tours lasting an hour and a half.
