5.00Slovenia was our first stop on the cruise trip. We hired this tour as according to what we were reading were the places that everyone recommended to visit. Initially we had booked this excursion with the cruise and it was cancelled GAD !!! I say GAD because I had to hire this tour and it was for the best. The guide was very friendly from the start and the whole journey from the port to the cave was giving us a lot of very interesting information to understand its history. Since we arrived at the cave the communication with him was very good as at all times he told us how many minutes we could be, where to head, etc... The Cave is a beautiful place impressive mind !!!!! We loved it. Just be prepared why it's cold. I was reading in different places that it was very cold and some people in my family did not believe me and had to buy sweatshirts there. Then the visit to the castle very nice, I just wish we could have come in. But it is the best tour in Slovenia!!
Gorgeous Caves

5.00Definitely one of the highlights of our trip. The tour through the cave was breathtaking and the stone castle afterwards was gorgeous. Just don’t forget a sweater like we did as the cave can be a little chilly, however, we are from Canada, so it didn’t bother us too much. Would highly recommend!
Exceptional/breath taking.
