Postojna Cave Tours

The essential things to know before you visit to Postojna Cave.

Although Postojna Cave is toured by millions of visitors, we have made sure the tour of our subterranean marvel is an enjoyable and one-of-a-kind experience for every single visitor. 

Open Year-Round

Postojna Cave is open year-round, including on Sundays and public holidays. From May to October, tours are available every hour and in the off-season three or four times a day.

90 Enjoyable Minutes, 5 Unforgettable Kilometres

Cave tours take about an hour and a half, during which you get to see about 5 kilometres of the cave. Part of the tour is done by train and just over a kilometre on foot. The path through the cave has a non-slip concrete surface and is easily accessible. As there are no stairs, it is suitable for visitors with mobility impairments and for prams/buggies. 

Disabled persons

Pets

Children

The somewhat more hidden parts of the 24-kilometre-long cave system can be visited as part of adventure tours. Some of the tours require a good level of physical fitness and previous caving experience.

There Is No Such Thing as Bad Weather in the Cave

The cave has a constant temperature of 10 degrees Celsius. To make sure you are not cold, you should wear suitable footwear and clothing. Should you need one, rain jackets are available for hire (EUR 4). 

Baggage Storage

Visitors without their own means of transport can store their suitcases, backpacks, helmets and other travel gear in the lockers of the Expo pavilion or in front of the ticket office. Baggage storage is available free of charge.

No Pets inside the Cave 

In order to protect the fragile cave ecosystem and to make sure the pets are safe, pets are not allowed inside Postojna Cave. But there is no need to worry – during your cave tour, pets can wait in the two pleasant kennels available free of charge. 

Tour Guide Services 

Each Postojna Cave tour is accompanied by tour guides, who provide visitors with tour commentary in Slovenian, Italian, English or German, presenting the cave's splendours in detail. Visitors can also use audio guides available in no fewer than 17 languages (Slovenian, Croatian, English, German, Italian, French, Hungarian, Spanish, Portuguese, Dutch, Russian, Polish, Czech, Hebrew, Chinese, Japanese and Korean).

Audio guide hire costs EUR 3.

Taking Photos

For the sake of preserving the delicate cave environment and ensuring safety, there are some limitations regarding taking photos during Postojna Cave tours. During regular cave tours, you are allowed to take photos and make videos, but without a flash or a tripod. Audio or video recording of the tour guide commentary is not allowed. Photographing and filming for commercial or other purposes requires a prior arrangement, so you are kindly asked to contact us.

Share your photos with your friends and post them on social media using the hashtags #postojnacave, #predjamacastle or #hoteljama. 

Cave Etiquette 

It took nature millions of years to create Postojna Cave, so we need to make sure it is preserved for future generations. A visit to this special place is a privilege, therefore it is important for all visitors to behave respectfully towards both the cave and other visitors. During the tour, our staff will guide and steer you in a way that will make sure the tour is a safe and enjoyable experience for everyone.
