Slovenia Tour - We left in an eight-seater bus. The guide was kind and taught us about Slovenian history and nature. The Postojna Cave was a sight to behold, and the Prejama Castle was also a great sight to see as it merged with the rock face. We then went to Pirang, where we had a walking guided tour and less than an hour of free time before and after. We enjoyed seafood gourmet food and strolling by the sea. Some of the tour went to the Skocjan caves, and I wanted to go there next time.

A great tour to maximise your day - What a superb day ! The tour was planned so well through a company called To Do In Slovenia ! Prompt what’s app messages since they had to re shuffle the date for us , a quick call when required, polite staff . The day itself started perfectly with a sharp on time pick up , very spacious and comfortable mini van , a small group of people and an excellent driver guide ! The caves and castle was lovely but th surprise package was Piran . It’s really stunning and a must visit are some of the restaurants on the coast . A full a very memorable day well spent. Thank you

Beautiful day, complete and guided from A to Z. - A full day, turnkey, suitable for a solo person (even if I was the only one). I recommend 100% to visit beautiful sights in Slovenia in just one day. The caves are beautiful, the cave castle also and the small town of Piran is very friendly (even if not really impressive) which allows a nice walk to close the day. Just a small flat: no slot really planned for the meal before 2-3pm. I personally had a sandwich at the end of a visit, but it wasn't set in the agenda. The driver was friendly, very clear and understandable in his explanations.

Great guide and trips with a mix of key Slovenian attractions and a taste of the med! - Amazing trip seeing some of Slovenia’s highlights. The teens rated a 10 and that speaks volumes. The castle was beautiful and very well done with the audio in all the rooms. The cave was epic and other worldly and the train added a fun factor and Piran was a beauty! Fantastic guide - do it, you will not regret!

Super Day - Super Guide - We had a fantastic day, we visited Predjama Castle before moving on to Postojna Caves. Both were awesome. Afterwards a short drive to the beautiful town of Piran for some free time and a guided walk which I'd recommend as you get lost through all the alleyways. Meha our guide was knowledgeable, friendly and a really nice guy. 10/10. Thank you for the full and active day
