Full description

What makes Ljubljana special is not only its cultural heritage, though it was once and still is a place of many great minds. From a traveler's perspective, it is an exceptionally good starting point for exploring Slovenia’s mountains, valleys, seasides, rivers, caves, and forests. It is well connected with other towns and basically halfway to anywhere. The old city center has a unique architectural appearance, particularly due to a felicitous combination of Baroque and Art Nouveau architecture and masterful creations by the 20th-century architect Joze Pleznik. Visit Ljubljana and walk around the city to soak up its vibrant atmosphere. Discover why the Triple Bridge is actually triple, where locals buy their food, how Napoleon was one of the most popular politicians, why Slovenia really lives with LOVE in its name, and much more. From Ljubljana, continue to the Karst region of Slovenia and discover the underground world of Postojna Cave, the most popular karst cave in the world. First, ride an underground electric train into the cave, followed by a guided tour through the beautiful passages and chambers with spectacular drop stones, pillars, limestone curtains, and other unforgettable forms.

It was a very interesting trip. Unfortunately we weren't able to get a guided tour of predjama castle because it was late in the season, but we did visit it and it was amazing. A scheduled bathroom break driving to and from Slovenia would have been good. Could have asked but didn't.

Our driver, who was our guide as well, was excellent! He was very friendly and dedicated. During the tour, he shared with us his deep knowledge on the history of Croatia and Slovenia. His knowledge was far beyond that of ordinary guides. Thanks to his explanation, we enjoyed the tour more. Although we had a minor problem on the schedule, he made his best effort to re-arrange our schedule.
