Pretty villages, forest and some spectacular views make this an excellent sightseeing road that runs deep into the forest.
The visibility is not always great so its not really a road for speed junkies but there are more animals than people so its very nice if you like nature.
The surface is ok, in places very good and in places a little bumpy. Around Evisa there can be some tourist coaches. After Evisa the road becomes a more typical Corsican mountain road with better surface and more open corners.
