magnificent view of Lake Geneva, Salève and Mont Blanc

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.

Very nice view when you get to the top, but it takes a lot of effort even on an electric mountain bike.

This metal bridge spans the Rhone. It offers a beautiful view of the river on one side and an impressive view of the motorway viaduct from below on the other.
