World-famous Postojna Cave
Guiness record Predjama Castle
Unique Slovenian Karst
Postojna Cave is the cradle of cave explorations in the world and one of the most visited attractions in Slovenia. Start with an exciting train ride that will take you deep underground to the towering halls of Postojna Cave. Join a walking tour through the unique world of dripstones and halls, all created millions of years ago, and learn about the active growth of the cave as well as the enigmatic fauna inside it.
Meet an incredible creature, the olm, which lives inside these caves and is oddly called “the human fish” (človeška ribica) in Slovenian and nicknamed “the baby dragon” due to its visual similarities to the mythological beast. This spectacular place below the surface has been visited for the last 200 years by people from around the world.
Our next stop will be Predjama Castle, a unique medieval structure built into a sheer cliff around the mouth of a cave. It boasts a Guinness book of records entry as the largest cave castle in the world and was home to the legendary Erazem of Predjama, a rogue knight whose story rivals that of Robin Hood. Optionally, take an audio-guided tour through the multiple levels of the castle (there are roughly 200 steps inside) or take in the panorama from the outside while enjoying a drink or a picnic.

Frequently Asked Questions
I am a single traveller, how can I book?
Don’t worry, just drop us a line in our inbox. We will do our best to try and find you some company, so if you are flexible in your travel dates, let us know as well. Do you want a private trip? No problem, we got you covered too.
Where do we meet for the day trip?
There are 4 designated pickup and drop-off locations that we use in downtown Ljubljana (see the options when booking). Your driver will be driving between multiple pickup locations, so we kindly ask you to allow a 20-minute window for your pickup, although we will do our best to be there on time.
In case you would like to be picked up / dropped off at a different location, we can accommodate that with a surcharge of 9€/booking.
Is there lunch at a restaurant or do I have to bring my own?
You have the option of both. We have a time slot reserved for lunch on each tour, always somewhere with (usually local) restaurants handy. That said, you can always pack your own picnic lunch and eat it wherever and whenever you like. This might sometimes even save time in order to fit a bit of extra sightseeing into your day.
How fit do I need to be for Postojna cave & Predjama castle day trip?
The best thing about our day trips is that they can be tailored to your own level of fitness. Most of the tours are designed with different activities available, so the choice is entirely yours. Please consult the difficulty section under a specific day trip to see what the difficulty level of the tour and particular activity is.
I am travelling on a budget - what if I can’t afford all the extras?
Don’t worry. Our day trips are planned with everyone in mind. If you find an entrance fee too expensive, or you are unsure if you are willing to spend so much of your budget on entrance fees, our guides will always have some free alternatives ready for you. From taking a short hike and finding that perfect photo opportunity, to relaxing in a beautiful spot, we have got you covered.
Will I have some time to myself?
If you want to, sure! We are well aware that some people love to stay in groups while others prefer some more alone time on their trip. We wanted to give you the opportunity to do things your way. It is your holiday, after all! As long as you respect the group timings and locations designated by your guide, please feel free to customize your itinerary and create your own adventure!
What should I wear? Do I have to bring anything with me?
It is important to dress for the season. Slovenia has all 4 seasons, so please check the weather forecast before the day trip regarding temperatures and rainfall. When you are close to the Alps, the weather can change fairly quickly, so your best bet is to always bring an extra layer. We recommend shoes you will be comfortable in. If you are visiting caves, please remember that the caves are cold in the summer, as the cave temperature is constant throughout the year.
I have food restrictions. Are there restaurants for me?
It really depends on the level of your restriction. Vegetarian options are fairly easy to find in Slovenia, but vegan dishes, on the other hand, are extremely hard to come by in rural areas of the country and in smaller towns. Please note, that the places where we stop off at for lunch are often traditional and may have difficulties accommodating you outside of their standard menu. We suggest you keep this in mind.
How do the “extras” work?
There is so much to do in Slovenia, so we wanted to give you the option of choosing exactly how you would like to spend your time here. Which is why we have compiled a list of popular activities in the areas of your visit and categorized them as extras. Therefore, the choice of which and how many you would like to experience is entirely up to you. We set up some of the most popular activities in the areas of your visit and listed them as extras. The choice of how many and which you would like to do is entirely yours. When you arrive to a destination, such as Lake Bled, the itinerary always allows for any additional activities you might want to do, like visiting Bled Castle or taking a traditional boat ride to the island. You can book all of your chosen extras in advance. Your guide will confirm the bookings with you on the tour and make sure you know everything you need to know. It is always exciting when people come away from the same trip enriched by different adventures and can share and compare their experiences along with the tons of photos they have taken.
At first was not thrilled about visiting a cave, thought caves are not for me, but this is so incredible. So happy I went, was a very comfortable visit.
Amazing experience, could not believe nature can make something like that. You can take your time in the cave, lasts quite a while. I also took some of the greatest photos of my trip in front of famos castle.
I loved the fact we got to choose if we wanted to go to Predjama castle or not. Me and my boyfriend had enough of museums and wanted coffee instead, so we got to enjoy the view of the castle.
