The mine spans a total of over 800 kilometers of underground tunnels.
The site served as a functional lead and zinc mine from the 17th century until its closure in 1994.
Underground kayaking takes place in flooded mining tunnels that have filled with water since the pumps were turned off.
The mine tunnel system traverses directly beneath the Peca mountain massif, crossing the border region between Slovenia and Austria.
A portion of the mine was transformed into a museum following the ecological rehabilitation of the site.
The train ride into the mountain follows the original transport route used by miners to reach deep extraction galleries.
Podzemlje Pece is a subterranean mining museum located within the abandoned lead and zinc mines of Mount Peca in Slovenia. Visitors explore the network of tunnels via an underground train that travels 3.5 kilometers into the mountain. The museum showcases the technical history of mining, including original machinery and tools used during the 350-year operational period of the mine. A specialized route allows visitors to traverse the flooded tunnels by kayak, guided by instructors. The site operates as a geological and mining heritage center with climate-controlled exhibition spaces. The facility maintains a constant underground temperature of 10 degrees Celsius throughout the year. It provides access to the 'Ulica rudarjev' (Miners' Street) exhibit, which illustrates the evolution of mining techniques. The site is a point of interest for both industrial history enthusiasts and adventure tourists.
The underground train tracks and the illuminated, flooded kayak tunnels provide the most unique photographic opportunities.
Bring a warm jacket and sturdy, closed-toe footwear, as the underground temperature remains at 10 degrees Celsius year-round.
Book guided tours or kayak excursions well in advance, as group sizes are limited by safety regulations.
Use the provided protective gear (helmets and lamps) strictly as instructed by your guide.
Attempting to explore the tunnel system independently without a guide; entering restricted zones marked with safety warnings.
Closed on Mondays; operations may be subject to seasonal maintenance or safety checks in the tunnel system.
Visitors must wear protective helmets provided by the museum; stay strictly within designated paths and follow guide instructions.
