Next, head to the Predjama Castle, a storybook castle wedged beneath a dramatic stone archway and against cliff.

Traveller Tips

The castle visit is a must - you will need to climb steep steps to reach the top - well worth it.
a beautiful little castle doesn't take long to get round but worth the visit, interesting to see the different levels build over the cave that was once also lived in.
If you feel comfortable driving then you could easily save money and drive yourself.

The sheer size of the cave and the distance we travelled inside. The caste which was amazing in that it was built in such a precarious situation and that it is still exists
See the sites in comfort

Vladimir provided swift, clean, and cool travel to two of Slovenia’s most notable tourist locations. Each location was amazing in its own special way.
susan_r, Jun 2022
We had a wonderful time on our tour. The castle was Amazing too. The coolness of the cave helped because it was so hot out side.
Great Destinations, Irritating Driver
James_L, May 2022
The caves and castle were fantastic. The drive was smooth. But the driver Vladamir never stopped talking, and the "talking" was stream of consciousness with no breaks between sentences. And in a monotone. He looked like Ozzy Osborne and sounded like him too. Very irritating.

Fantastic trip to Postojna Cave and Predjama Castle
Eric_D, Jan 2022
The trip to the cave and the castle was fantastic. Our guide was very friendly and funny as well; we did enjoy all the explanations given as well as the organization of the trip. Thanks a lot for this lovely journey.
Lovely trip with an amusing guide
maryam_a, Jan 2022
The trip was well managed and wonderful. The guide did not bore us during the long rides to the attractions and shared great knowledge about Slovenia. We only had a few inquires that were not answered to directly, not sure why. Maybe it was not clear or the guide was focused on giving the information that he knows as part of the trip’s agenda. However, all in all, it was a good one. Worth to mention thought that the cave and the castle are provided with audio guides so the tour guide is usually waiting for you outside the attraction…
A fab day trip for when you’re in Bled
Michael_P, Sept 2021
We really enjoyed our trip to the caves and to the castle in Predjama. The tickets were sorted for the caves for us. We just had to go in at the right time and really didn’t have much to worry about as the guide sorted it for us. Our guide was absolutely bonkers but highly amusing.
