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.

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.

This was an amazing trip! I’m traveling solo and thought it would be fun to visit Slovenia for a day. It was so beautiful I want to plan another trip just to go there! My tour guide, Antonio, made the experience great. He knowledge of history surpassed any guide I’ve had on a trip anywhere (and I’ve been to almost 40 countries). Also he was extremely patient & kind helping me to take dozens of photos (I’m a picky girl & gotta have the right angle haha). It was a fun tour solo too because I met several nice people. The bus holds 8 so it was cool meeting other travelers. I would recommend this trip to anyone. It was well worth it! The caves and castle were spectacular & I’m definitely visiting the city again someday :)

Excellent day's outing

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.
