From le Sauvage near Abondance go to the col de la Plagne du Mont.
At the right, reach the crest over lapiaz-stones. Follow the crest line and climb down any blocks (first difficulty II) At the summit of the Dent du Chien rope down the "Saut du Chien" (rope rings). A funambulic trip of 2 km begins ! The rocky crest becomes more an more slender. Before the summit, a discharging wall must be climbed (III). I give advice to descent the normal route.
Rope useful and adviced, helmet, climb-belt, snaps.
