Nestled in the Semine valley, Saint-Germain-de-Joux offers a preserved natural setting. Don't miss the "marmites de géants" (giant's cauldrons), these rock formations carved by water, accessible from the village.

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.

A 10 km climb from the small roundabout in Châtillon, it's more like 14 km from the Nantua road or the center of Bellegarde. The gradient is fairly steady, ranging from 5.5% to 7.2%, with about ten small steep sections at +8.5%. Very quiet, with very few cars. The road is generally in good condition, but nothing more. There are some beautiful views along the way.

A beautiful road through the forest up to the plateau. Numerous ramps, interspersed with short breaks for rest. The road is consistently well-maintained. There are almost never any cars, but when there are, it can be a bit of a squeeze.
