Are you ready to traverse a forest suspended above the Val d'Ambin? Starting from Le Cernay, the warm-up is short as far as La Villette. The ubac route then seems a little steep for the first hour, but there are plenty of cool breaks along the Laméranche stream.
The combe des Archettes suddenly welcomes you, opening up onto a grazed clearing. The patous keep a watchful eye on their herd. Fear not, stay on your well-trodden path. But what are those curious gypsum formations to your left? The ridges of Général Sarret will soon make you forget the 800 m you've already climbed.
Stop off near Lac de l'émeraude and take in the Mont Froid fort. The former military barracks bear witness to a rich military history. The detour was well worth the 360° panorama!
Return to your original route to reach the Petit Mont Cenis plateau. Surrounded by peaks as wild as they are fascinating, enjoy the fresh air at 2639 m altitude.
Soon it's time for a quiet descent, with all those memories in your travel diary.
