Imagine this: You’re in a boat. Underground. The impeccable silence is broken only by the water dripping from ancient dripstones, animal chatter, the occasional splash of your paddle as you make your way into the subterranean world, and the voice of your guide unlocking the mysteries of this extraordinary place. Sounds poetic and appealing? That’s because it is.

Clean, unspoilt, diverse caves and water systems is what Slovenia is famous for, and on this unique boat trip you get to explore both within the confines of the magical Planina Cave. It boasts remarkable biodiversity and is home to 60 aquatic and 40 land species. Among them is the endemic cave-dwelling aquatic salamander known as the olm or “human fish” (Proteus anguinus). Planina Cave has the largest population of these bizarrely beautiful creatures roaming its depths. Spectacular!

Other special features of the cave include a variety of chambers, numerous underground lakes and impressive rock formations. Located right next to Postojna, the Planina Cave is almost seven kilometres long and believed to be the largest water cave in Slovenia. Check it out for yourselves!

Our Underground boat adventure is available 7 days a week, all-year-round. It lasts approximately 4 hours, with the recommended starting time between 08:00 and 12:00

As the mine has a constant temperature of 10 °C, visitors are encouraged to wear appropriate clothing and walking or hiking shoes. The rest of the kayaking and safety equipment will be provided onsite.

No. You’ll be accompanied by a professional guide who will lead you safely down the underground world. All you have to do is paddle and enjoy the ride.

Children older than 10 years old are welcome on the tour as long as they are accompanied by a parent.
