Via Ferrata is a route to be climbed on foot on a steep rock. Its access is facilitated by rungs fixed to the rock. 460 meters long, with a drop of 125 meters and an inclination of the rock wall of 75 degrees, the via Ferrata straddles the waterfalls of the Tière torrent on three occasions thanks to footbridges.
