Slovenia’s wonderfully diverse landscape offers a wide array of cycling adventures. The country is criss-crossed with fantastic urban and rural cycling paths and mountain biking routes. But what if we told you that cycling doesn’t have to be limited to trails aboveground?

Sure, mountain bikes are meant for the slopes of hilly and forest-covered terrain, but let’s take this sport up a level. Or down, to be precise. Thanks to its rich mining history, the incredibly picturesque region of northern Slovenia called Koroška (Carinthia) is as captivating below as it is above. Once such a place is the subterranean world of Koroška’s beautiful Mount Peca. According to legend, the mountain is home to a slumbering king, who will one day awaken to bring prosperity to the land. Myths aside, the underground realm of Mount Peca is fascinating to explore and to do so on a bike is truly an epic experience.

Our adventure begins at the entrance to an old abandoned mine. A guide will then lead you down 5 km of the mountain’s mysterious underground tunnels which lead to another valley on the other side. Besides cool mountain bikes, you’ll also receive helmets fitted with flashlights. The path runs through secure tunnels with an elevation rise of only about 15 m, which means an easy ride awaits. That said, the mine’s former railway has left plenty of potholes to guarantee a bumpy and exciting experience. All you have to do is hold on, marvel at the underground passages, and enjoy the ride!

We took the 4-hour "City Bike Tour Ljubljana" with our guide, Andrej. Andrej was fabulous: filled with informative, historical, and humorous details. The ride allowed us to see many parts of Ljubljana in a short time, and Andrej tied it all together. The ride was not too difficult (we are seniors). The lunch stop was perfect (Slovenian charcuterie, plus a pour of local wine): enough to eat, water to drink, and a convenient WC. We recommend this tour (and Andrej) without reservation. We could not hope for a better experience.

This was a truly amazing experience! We really enjoyed our beautiful Seven Lakes Valley hike with an overnight stay at a mountain hut. The alpine scenery of mountains throughout the hike was simply stunning especially the crystal clear emerald lakes, which are absolutely breathtaking! The cosy mountain hut was a lifesaver after a long day’s hike, dinner was hearty and delicious, atmosphere was lively and the beds were warm and comfortable - overall a great experience! What made it all the more enjoyable was being in the safe hands of our brilliant guide, Klemen who was not only very experienced, professional and knowledgeable, but he was also extremely helpful and accommodating. He went out of his way to take care of our needs during the journey. From the start, he was very responsive and proactive in helping us arrange our itinerary in the best way possible to maximise our time there. We also did a private rock climbing session with him after the hike and it was awesome! We definitely enjoyed our time in Slovenia with him and highly recommend going with this company and a private guide like him if you are looking for a customised trip.

While in Slovenia we really wanted to go cave kayaking. We had booked in weeks in advance, but when we arrived another company cancelled our trip as it was off season and they didn't have enough people interested in doing it. We rang around some other companies and kept hearing the same thing, until we contacted Slovenia Activities. They usually need a minimum of four people but said they would make an exception for us (there were two of us). They arranged transport and that's when we met our driver Peter. It was a long drive, nearly two hours, but didn't feel long at all! Peter was so chatty and funny that the time flew by. We were taken back by all the beautiful scenery so he offered multiple times to make a stop so we could get some photos, he also bought us some bottles of water. The actual trip is quite physically active so you need to be on reasonable shape as there are a lot of steep stairs in the cave. You start off going in a miners train, and then go to a to where you put some waterproof overalls on. If you have a shoe size over 38 then the overalls have a waterproof pocket at the front where you can keep your phone. The actually kayaking was fun, you are allowed to explore it on your own and at the end of that part you go down a mini waterfall! Then after that you explore the mine and end on a miners meal of a meat platter, some bread and some spreadable cheese. On the journey back Peter was a delight again, and let us stop at McDonalds to get some dinner.

Had a great photo tour around Ljubljana with Nejc. He understands a lot about photography and also about the city and history of Slovenia. Visited a lot of photo spots in 4+ hours and he was also willing to share his knowledge around how to get great photos. He is also very friendly and reliable. Thank you so much Nejc and Slovenia Activities. Highly recommended!

I had an excellent time on my tour! Anze was friendly, detailed, and patient on our caving Lake Bled adventure caving tour. It has inspired me to further explore caves in my own region.
