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!
