Postojna Cave with Kids: Uncover the Adventure

Yes, you should visit Postojna Cave with Kids. If you were wondering. We’ve done it and here’s what makes it a perfect family destination: great outing in any kind of weather, the train ride around the cave, with little walking makes it suitable for kids of all ages and it’s stunning – nothing like you or the kids have seen thus far. Here are our tips to make it happen.

Postojna Cave – a magical kingdome

I visited Postojna Cave ages ago. As a kid myself. And what I recall most about it, even years later, is being awe struck that such a place exsists underneath. A magical kingdome.

Fast forward to present day and the memory faded. As the cave became a major tourist attraction in Slovenia, I became convinced it might be just that. An attraction. For tourists.

Then I had kids and these girls of mine are born explorers and they still belive the world is a magical place. And that’s when it hit me!

I’ll show them Postojna Cave to reaffirm their belief – that the world truly is a magical place.

About Postojna Cave

We are talking about 24 km long cave system created by the Pivka River millions of years ago.

Of course you can’t see it all, but your visit will take you through 5 km of the best parts. 3,7 of these you cover by a small train and the rest you walk. All the time you marvel at Nature’s grand work – the stalactites and stalagmites of all shapes and sizes. 

This year marks 200 year since the discovery of the largest part of the cave.

Postojna Cave with kids?

The visit, both the train ride and the path are suitable for kids of all ages, even if you have one in the pram. Though you’ll have to push it up hill a bit. Up the Great Mountain – doesn’t it sound very Lord of the Rings, or is it just me?

The likeness doesn’t end there – because you won’t believe it, there’s also a bridge, called Russian bridge, that you get to cross, right in the cave. And it takes you to the aptly named Beautiful Caves, where the symbol of Postojna Cave, the Brilliant stalagmite awaits you.

The whole adventure lasts about 90 minutes.

And you also get to meet baby dragons, which kids will find fascinating. We are of course talking about olms. The unique creatures are considered the largest cave-dwelling animal that can go without food for up to 10 years.

Where is Postojna Cave?

We went by car, which is very easy. Get on the A1 highway from Ljubljana to Koper and follow signs for Postojna, then the signs for Postojna Cave and it will take you right to the parking lot.

The parking costs 5 Euros per day.

When to go?

The cave is open all year round, including public holidays. But since you can’t just get there and go in whenever you’d like, check the official website for tour times.

During the Summer season there are more tours, while in the Winter with the exception of December there are less. Book in advance is my suggestion.

Don’t forget! The temperature in the cave is around 9 to 10 degrees Celisius, which in the Summer can mean a huge difference between the outside and inside temperature.

If you are visiting in the Summer take additional clothing and put on sneakers, leave the flip flops in the car.


Again this depends if you are visiting during high or low season. Adult tickets in the low season (3. 9. 2018 – 27. 6. 2019) are 25,8 euros, while in the high season (28. 6. 2019 – 2. 9. 2019) 27,90.

Check out more on the official website.

You can also combine the visit to the cave with other sights located near by and get a reduced price. We combined Postojna Cave with the visit of the Predjama Castle.

Kids about Postojna Cave

On our visit we’ve learned there are over 13.000 caves of different sizes in Slovenia. After Postojna Cave our girls have decided we must visit them all. We’re into caves now, so beware, your kids too might fall in love with them.

But I believe that’s their mission. At Postojna they are taking very good care of the cave while at the same time brining people in, visitors whose mere presence affects the fragile eco system. Why? To educate us about caves, Earth, make us care, fall in love even, or at least appreciate Nature and to realize how all our actions have consequences, even way below us.
