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.
