This was a wonderful trip! It was so flexible to what the group wanted!
Dramatic views of the cave. There’s a guide with you throughout the whole walk with explanations. No camera allowed and it’s really beautiful inside. Spent 2-3 hours in piran. Enough to look around and have lunch.
The tour of the caves is absolutely spectacular but also quite strenuous - it's a fair walk from the tickets office to the cave entrance then lots of steps and slopes within the cave system so it may not suit everyone..
Very nice tour, both the caves and the city of Piran. Our guide was very good, and we learnes a lot also about Slovenian history and life in general.
Cave was fantastic especially part with river rapids and waterfalls. It is a strenuous activity with lots of climbing 500 steps down and then back up. We were really tired.
We so loved our tour with Varun! Not only was he on time and very professional, but he gave us so much great information and tips to make our tour even better .m. We would absolutely book with them again and highly recommend!
Finished a week of driving around Slovienia with a few days in Ljubljana. Tourist load was just quieting down. No waits at all the amazing restaurants and patios. Weather was perfect. Most beautiful country I've been too. But the people are even better.
The Skocjan Caves are amazing! As an older person who loses her balance easily, I felt perfectly safe with all the handrails.
The tour was great. Loved seeing the horses, especially watching them practice. The caves were beautiful but included a lot of walking with lots of steps. Matt, our guide was terrific. He took care of us the whole time.
