Excellent trip, well worth it

Excellent trip with an excellent host. Castle and cave were brilliant. Something quite magical about the cave. Only small downside was that after the cave visit it felt a little rushed. The cave was busy so had to queue.

Gorgeous sites, well organised and informative tour

Great tour, excellent and well-informed driver/guide, everything was pretty well ordered and we got to the right locations as planned, with swift entries etc. For me, I would have preferred to have had a tiny bit more time at the castle but suspect each person has their own limits with that type of thing!

I had an absolutely...

I had an absolutely unforgettable experience visiting Postojna Cave in Slovenia. The cave itself is breathtaking, with massive stalactites and hidden chambers. The highlight was definitely the train tour—such a front-row seat to the cave’s magic. We did book a private small group tour, but unfortunately, it ended up being a large bus with a lot of cruise passengers, which was a bit disappointing. Still, the cave itself and the guide were phenomenal—it’s a must-see in Slovenia!
