About 2 kilometres before Sopot, six entrances located in a rocky wall above the left bank of the Sora lead to Matjaž’s Chambers. These are the remains of a formerly active water cave formed by the Sora. Matjaž’s Chambers are a real labyrinth of tunnels on several floors including stalactites and the phenomenon of cave milk appearing on their walls. The length of the tunnels is approximately 500 metres. Alongside archaeological excavations (for the remains of stone tools used by ice age hunters), the remains of ice age fauna were also found.
