In my opinion, this is a terrible road for a road bike. I don't enjoy cycling back, but the "view" from my perspective isn't worth the ride, as most of it is trees and you only get a brief glimpse of the lake or the valley below, not to mention the Salève. The road is already very bad a few kilometers past Thoiry and only gets worse. I continued past the viewpoint, hoping to eventually reach a decent paved section. However, that didn't happen until the descent to Crozet. Of course, this isn't a problem on a gravel bike or mountain bike. I was glad I didn't get a flat tire.
