The via ferrata of Tellure mining park constitutes an intermediate activity between caving and climbing. A path specially designed for practicing climbing has been traced in the galleries. In semi-autonomy, the lifeline allows self-belaying. Visitors work their way up the rocky face using cables, steps, and ladders. The course enables following the traces of the women, men, and children who flocked to the region during the 16th-century silver fever. Residues of copper, lead, and silver still emerge from the gneiss walls of the cave.
