This is a challenging hike, with some very vertiginous sections. You will finish in the village of Venosc and return by gondola (check opening hours).
An amazing view awaits you at the top, with a breathtaking panorama of the surrounding mountains. The descent to Venosc will take you through forests of hundred-year-old fir trees, mountain hamlets in remote Alpine meadows, but also some scree slopes where it is best not to linger.
