The underground of Pec - a unique underground cycling and canoeing adventure through abandoned mine tunnels.Thanks to centuries of excavations in the mines below Pec, thousands of kilometres of tunnels have been created, which can be explored in different ways. You can take a train to the heart of the mountain and walk along the museum trail. The more adventurous can explore the museum trail on a well-maintained cycle path with headlamps or go on a kayaking adventure through the underground lakes.
