Magnificent view of the Robines, slopes formed of black marl. These sedimentary rocks were found at the bottom of the seas in the secondary era. Later, the formation of mountains brought up its soils which shelter numerous fossils (ammonites, algae, plants).

At the bend of a hairpin bend, this egg is a work of Andy Goldsworthy. This is one of the three “Sentinels” of the Refuge d’Art course; it represents the Asse valley.

On the western slope, after going up the long Asse de Clumanc Valley from Barrême, the difficulties really begin in Tartonne with a first ramp of 1.5 km at 6.5%. Then after a small flat area comes a nice final of 2.6 km where the slope will be around 7%. On this side you can see one of Andy Goldsworthy's sentinels, an ovoid-shaped cairn placed at the side of the road as part of an artistic trail created by this renowned artist practicing land art. On the eastern slope, nothing very complicated until Lambruisse with 5 km where the hardest passage will not exceed 4.5%. On the other hand, things become tougher with the final including 1.8 km at 6.5% on average, but the last 350 meters are at 8.5%. The road is very beautiful and quiet on both sides. This pass is enchanting.
