Great guide and great sites. What else can you ask for?

We loved this day tour. It never felt like we were spinning our wheels and it never felt rushed either. Our guide Primus (spelling?) was friendly and open to answering any questions. I had a lot of them and he gave me thorough and thoughtful answers. Talking to him is better than going to a museum. It was like a university course in the van (not boring though). He was so kind he would line up with us at each venue to ensure all eight of us were together and going to the right place. He offered to take pictures of everyone at certain spots as well. He gave us the choice of starting at the castle or starting in Piran. In addition to an excellent guide, this tour is full of sites that are unique and unforgettable. This tour is just packed with wonderful things to see. We were genuinely glad we did this. It was a highlight.

Very enjoyable day with a great tour guide

Hesitated about booking as with entrance fees it worked out at about 300 Euro for two people but had a great day. Mini van was comfortable and cool. DJ was a very good guide, informative, friendly and helpful. He was also very patient as the other group were always late. We travelled to Piran on a very hot day but the journey was cool. We started up on the walls and the steps are steep but the views are worth it. Piran was lovely, great place to look around with a great square to have lunch and sit in the shade of the umbrellas. Predjama Castle was fabulous, picturesque and very interesting. There's a free audio guide. Really enjoyed it but there are many steps. Postojna cave, interesting and worth doing though we did find it a bit samey after a while. The reviews I read said it was worth it and I have to agree, one of the highlights of our visit.

Interesting but not spectacular

A lot a steep steps might be a problem for older travelers. The cave tour was interesting if you have never been to a cave experience before. There was too much time spent on our own in Piran. The guide/driver was great. The group size was good (8).

Lovely time exploring the Slovenian coast

We had a really great time seeing Postojna, Predjama and Piran with Nate. He was a great guide, full of interesting information and tips for seeing everything and always ready to help answer questions or give advice. We’d love to come back.

Great tour

Due to unforeseen circumstances, they switched my full day tour to half day afternoon tour (only the cave and castle but with tickets covered). Things still worked out. Appreciated Matt the tour guide's enthusiasm and knowledge, also the little thoughtful surprise at the end of our cave tour. The cave is a must-see!

Warm, Welcoming, and Wonderfully Informative

Nate was an amazing guide who really knew his stuff, and he made everyone feel welcome and included, even visitors with disabilities. The tour to Postojna Caves was truly incredible, and hearing the stories along the way made the whole experience even better. He also introduced us to some local liquor and pointed us toward a few great spots nearby, which we really appreciated. What stood out most was how comfortable he made everyone feel. He created a genuinely warm, welcoming atmosphere where people could interact with each other and ask questions freely, without ever feeling awkward. Highly recommend this tour! The only improvement I'd suggest is having the location tickets prepaid and bundled into the main price.

So much fun!

DJ was amazing! The castle/cave fee wasn’t too bad, especially since it was high season (we are students which helped). The whole day was carefully planned and DJ kept us well informed and entertained. There was only 6 of us in the group which made it more enjoyable and felt more personable. We would highly recommend for anyone wanting a day out exploring, without having to do your own travel arrangements! Thanks again DJ :))

Coast, castle and cave all in one day

Had a brilliant time on this tour on my last day in Ljubljana. I wanted to see all 3 places (coast, castle, cave) and this tour was an easy way to do it all in one day. Piran was a highlight, a beautiful town and a lovely lunch. DJ was a great driver and gave us some of the history while on our way to the 3 stops. Thank you.
