The Underground Train Experience

One of the highlights of Postojna Cave is the underground train. The first 2 kilometers of the journey are covered by train, giving us a chance to experience the cave without tiring walking. After the train ride, we walk through large halls and narrow corridors with a guide explaining the cave’s formation. This combination makes the visit exciting, educational, and comfortable for most visitors.

Best Time to Visit

The cave maintains a constant temperature around 10°C (50°F) year-round.

- Spring and Autumn: Best for fewer crowds and flexible schedules

- Summer: Busiest time, more tours available but long queues

- Winter: Very quiet, but fewer tours—planning ahead is essential

We can enjoy the calm atmosphere anytime, but choosing spring or autumn helps us avoid crowds while still having plenty of tour options.

Postojna has several accommodation options, from budget to mid-range hotels:

Booking in advance is recommended, especially during peak tourist season.

We can enjoy a meal before or after visiting the cave at nearby restaurants:

- Restaurant Proteus: Main courses $12–$20, traditional Slovenian dishes

- Café Jama: Light meals, pastries, coffee $5–$10

- Nearby Town Cafes: Lunch menus $10–$15, ideal for quick stops

Carrying water and snacks is also a good idea since the underground temperature is cool and the tour lasts about 90 minutes.
