Subterranean adventures

Embark on an adventure by exploring the Peca underworld. More than a thousand kilometres of underground tunnels were excavated through centuries of mining.

Discover the wonders of the Peca underworld, a tourist mine that offers unique adventures and experiences under the Earth’s surface. Listen to the stories of the miners’ lives and explore the mysterious tunnels. An even longer tradition of tourist exploration of the Koroška underground can be observed in the Huda Luknja cave – a true subterranean gem of the isolated Karst which can be experienced on a guided adrenaline trek.
