After a long section of "classic" pass, we suddenly find ourselves on the side of a cliff with a majestic view 😍. The valley is not very long but magnificent. Many nooks and crannies to stop and take a photo.

A fairly demanding pass at first, but it eventually eases off as the scenery becomes incredible! 6 km at 8%, then 6%, 4%, 5% (not sure, I was just looking at the scenery) and the last two km at 4%.

Small pass on the D199, unfortunately without a pass sign. There is a small water source not far away.
