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.

On the Right Bank terroir, Mandement is the main wine-growing region in the canton of Geneva. Wine production in Geneva has its roots in Roman times. Generations of winegrowers and winemakers have perpetuated this tradition to bring to life increasingly noted vintages.

If you want to go to Mount Sion from Geneva to go to the Salève, I advise you to go through the Col de la Croix de Biche. It allows you to avoid the Annecy D1201 road, where traffic is dense and fast. Here, the road is much more peaceful.
