The visit to the caves was the great disappointment of the whole trip to Slovenia: They have no guides who speak Spanish and we made the mistake of taking the tickets (+140 €!!) with the guide in English. They joined us with +80 people with ONE GUIDE for all (watch, of the 90 minutes of the visit, 45 minutes spend waiting and getting on/off the train that travels the 3.5 km out and back, 15 minutes are kept at the end to ensure that you can spend money in the store that they have inside and in between they spend ONLY 30 MINUTES to walk the 1.5 km of cave that they allow in the visit, making ONLY 3 stops of the guide (who had to wait until they all joined) to give explanations, making the whole run, NO information of what we were seeing and NO time to stop to enjoy the visit. It's very sad considering that we scrolled from afar just to see them, and all to sell more tickets.
