Slovenia- Underground Biking - Mine Tour by Bike

Inquire Booking

Lead mining under the mountain Peca began already in Roman times, the written records show, that from 1665 until the end of the previous century, when the mine was finally closed down, 900 km of tunnels were dug under the mountains of Koroška region. Today Tourism Mine and Museum Podzemlje Pece is one of the main attractions of Geopark Karavanke (member of UNESCO heritage) and the place for unique underground adventures.

People usually seek mountain biking enjoyment in the mountains, but what we have found is the passage through the mountains, along our abandoned and mysterious tunnels, in the mine no longer in use under the Peca mountain. Majority of tunnels were dug out in the solid rock. The ore and the waste material were transported from the mine by special cars along transportation tracks. Nowadays, this unique, more than five kilometres long cycling route runs through such bike tunnels.

What we offer is a guided cycling tour, more than 5 km long, along a path, illuminated by head- lamps warn on helmets, from one valley to another, where you can enjoy a safe, extraordinary and unforgettable adventure.

The starting point for this adventure is the Mining museum in Mežica (500 metres above sea level), where the guide with the necessary equipment will be waiting for you. From there you will be shuttled 8 kilometres with van to the mine entrance Igrčevo (643 metres above sea level) near Črna na Koroškem.

The cycling path runs along safe tunnels and it rises for only fifteen metres, but the potholes and bumps which remained from the removed tracks do not offer smooth cycling. The guide will stop on some interpretations points and explain you about mining history. The mine exit is in another valley, (Breg near Mežica), from where you will descend along a two km long road back to The Mining Museum where about 2 hours long adventure will be finished.
