Really fantastic experience. Many thanks to your knowledgable driver and the wonderful kayak guide. We stopped at some really interesting places on the trip there which made the drive to the caves very enjoyable. A unique experience.

Fantastic day. The whole trip was an adventure. The entrance of the mine with the train, the walk down in the mine, the walk with the kajak and of course the kajak tour. Also the lunch with the local specialites was very good. If you look for a special experience: book this tour

It was great day out. Beautiful places, loads of history, and lots of adventure. Thank you for a fabulous day out. The train was fun, the 'miners snack' was appreciated. Great guides, especially our transport guide. Thank you.

This was more than expected! The drive through Slovenia and Austria to reach the mine was so picturesque and made even better with both the information provided by our driver Sasha, and the stops we made en route on the mountain passes. The black hole kayaking was so much fun, being allowed to go off "on our own" to explore the passages in the dark. Be prepared for walking up and down some steps to reach the kayaking stage but the lunch afterwards was a nice treat and they catered for gluten-free guests excellently too.

The trip was managed very nicely. We took a stop around Milka valley and Primo was explainign to us how the valley was named and allowed us time to laze around and take a few nice shots. The black hole kayaking experience was also very unique and nicely managed. They catered to my food requirements and provided me a nice vegetarian lunch upon the end of the trip. Highly recommended tour and the tour providers.

Absolutely brilliant. Truly a once in a lifetime experience. And Pr1motours were amazing. We also did the e-bike hire and clear kayaking with them, and they were superb.

Great and different experience. We enjoyed it very much. I would definitely recommend booking this tour and other tours with Primo.

Great service and friendly staff. Helped us with every question we had. Would reccomend to everyone 10/10

It was a great experience! The only "but" I could say is that it is bit far from Bled. But otherwise totally recommended!!

The underground kayaking in an abandoned mine is a really cool experience. Well organized transport made interesting with a few nice stops and interesting and fun facts and background about Slovenia.

The Black Hole Kayaking tour is definitely a highly recommended experience for everybody coming to Slovenia. The only bad thing about it — is it's hard to book, so you need to plan ahead.

Great trip. Primo took us along the mountain passes and showed us some pretty places of Slovenië. The kayaking in the mine was a great experience! I would recommend te book this trip!

We found this through Altitude Activities. Aleksandra drove us out there - taking a better route for our carsick daughter. She was always attentive to our needs and so clearly wanted us to all have a wonderful time. And we did: the cave kayaking is unlike anything we've ever done before. From the train in the pitch black to walking into the water in the 'fisherman's pants' it was obviously building up to something awesome. In the kayak, there's no current, so it's super-safe, even for children. Exploring the different caverns and mines is great fun. You look down at one point and the floor is 30m below you! A great day out. Thanks again to Altitude Activities for taking such good care of us!

Expert local knowledge and recommendations for the rest of our trip were brilliant. Hotel pickups were a nice touch and the tour guide was really engaging and passionate about showing the best of the area to us

This is a unique experience and a life-time memories. The whole day was very well orgenized. Not only the underground but also the journey from Bled was an amazing scenic drive. Special thanks to the tour guide. We stopped several place to take a photo. So this tour is absolutely recommended if you want a special experience and don't mind you will be tired by the end of day.

The black-hole kayaking is a fantastic and unique experience. Although the actual kayaking part is quite short (about 1hr) and there isn't a great deal of the cave to be explored in the kayak, it is made up for in the experience getting to and from the kayaks. The mini-bus journey where you stop off in the mountains to enjoy the fantastic views, the old mine train that takes you in and the walk back from the kayaks to the train where the guide explains some history of the mines all add up to a great day.

The black hole kayaking was a very cool and special experience. The organizer, pr1mo tours, was very professional. It was a smooth and flawless experience, from pick up to drop off. On the way back from the mine we got to see some beautiful places in Slovenia where we stopped and took some photographs. We would highly recommend this activity and pr1mo tours to others.

Absolutely loved the black hole kayaking - couldn’t recommend it more! Pr1motours run tours so frequently so we had no issue fitting it in before flying home (we had this problem with many other your agencies). The kayaking experience was amazing and definitely something you shouldn’t miss out on when visiting Slovenia! Phoebe & Joe

The Black Hole Kayaking tour is a unique experience; Thrilling, visual, and educational! Thanks to the team!
