There is musical performances and special lights settings which makes it extra beautiful and special. The tour started by taking a cave train, then It is a bit of a walk in the cave, about a 5km stretch but it's worth it, as you will be mesmerized by the beauty of the cave, especially in this special light setting. Wonderful day,…”

★★★★★★★★★★4.7 · 220 reviews · 11.5 hours · from $169

“Our guide, Basil, was so friendly and knowledgeable about his country. It really enhanced the tour when he was able to add lots of obscure facts and stories, and the small group meant we had more freedom to pick and choose. I would suggest doing Lake Bled in the morning as most things were closed for the day in the off season by the time the got there. Then doing the caves and castle on a separate day. The whole country is just stunning and deserves to be appreciate and experienced.”

13.Ljubljana, Postojna Cave & Predjama Castle Tour

★★★★★★★★★★4.9 · 71 reviews · 12 hours · from $141

Travel from Zagreb to Slovenia in a comfortable van with Wi-Fi, water, and a snack. Walk through Ljubljana, enter Predjama Castle built into a cave mouth, then ride an underground train through Postojna Cave. English-speaking guides such as Antonio, Dino, and Stephen have led this small-group day, which suits curious first-time visitors with warm clothes and good walking shoes.

“The organisation was outstanding and our two guides were very informative and interesting. Ljubljana is a beautiful little town where we had time to explore by ourselves after a tour around the centre. Predjama Castle is in a stunning setting and quite different to other castles I have seen. The cherry on the top was our excursion to Postojna Cave. The ride into the cave in the train was exciting as we saw more and more stalacmites, stalactites and columns. But that was nothing compared to what amazing caverns we walked through with the guide. Spectacular seems to be the best word to describe these formations.”
