Subterranean adventures

The exploration of the mysterious underworld, where the light of day never shines, is a special adventure on its own. You can explore the underground on foot, with kayaks or cycle from one valley to another by bike.

The ore deposits between Mount Peca and Uršlja Gora were discovered already by Romans. In the years of active mining, more than a thousand kilometres of tunnels were dug out, where you can still hear stories of the miners’ life and be amazed by nature’s wonders. The Peca Underground – Tourist Mine and Museum is one of the central tourist attractions of the cross-border UNESCO Karavanke Geopark with its selection of unique subterranean adventures and experiences. You can take a train to the heart of the mountain and continue on foot to explore the underworld. If you are looking for a more adrenaline-packed visit, you can explore the underground by cycling or rowing a kayak to the flooded parts of the tunnels. An even longer tradition of tourist exploration of the Koroška underground is held in the Huda Luknja cave, which is a real subterranean marvel of the isolated karst. Here you can experience a true adrenaline-packed trekking adventure with the help of a guide.

Huda luknja

Discover this subterranean gem of the isolated Karst, which is undoubtedly one of the largest natural sights of the Koroška and Šaleška regions. Huda Luknja is one of the oldest tourist caves in Slovenia and has been open for visitors since 1895. With its dimension and location next to the Velenje–Slovenj Gradec regional road, it sparks curiosity and always seems to surprise both the visitors and the researchers, since it hides a number of sights inside and in the surroundings. Up to this day, more than 2,900 metres of the cave have been researched, however experts believe there is a much larger cave system to be explored. The underground surface where you can walk and crawl is about 1,600 metres long.

The karst underground is an increasingly popular form of actively spending leisure time. Experience the unforgettable subterranean adventure! Professional and skilled speleologists will take you into the depths of the cave where you will spend four hours rather differently. First, you will head out through Lisičnica, which is one of the access points into the Huda Luknja cave. After a few defiles and two siphons, you will have to crawl, relatively dry, to the ‘bear tunnel’ (Medvedji Rov), which is in this part buried under deposits of gravel and clay, and where you can also spot some bones of cave bears.

Then you will take a walk around the large hall of the Medvedji Rov tunnel with magnificent dripstone structures, from cave curtains, stalagmites, stalactites, pans and really thin pipes. If you are lucky, you might even meet one of the bats living in the cave. The path is cut off at the end of the tunnel with a 30-metre abyss, meaning you will have to turn back and follow the same path again, enjoying the cave beauty once more.

What do you need? You will receive all the needed equipment before entering the cave. All visitors must be in good physical condition and wear warm clothes.

Those who have already experienced the cave, claim it is very hard to describe their feelings, which were also felt by the first researchers of this karst beauty. Let us preserve it for our offspring.
