After 10 km of difficult climb, 10 km mid-mountain false plas in the forest, 10 km of descent facing 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.

Take time to admire the vast view that stretches from the city of Geneva to the majestic peaks of the Alps, passing by the serene waters of the lake.

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.
