Nestled in pastures at an altitude of 1,000 meters, Giron is the highest (and sunniest!) village in the Ain. Welcoming, with breathtaking views, it is ideal for an overnight stop.

Pretty little lake in the heart of the small Jura mountains

A typical Jura ridge trail: cliff on one side, forest on the other, sharp rocks and large roots peeking out, and constant steep sections (uphill and downhill). It's not the worst I've seen: aside from the steep sections, no section is technically impossible for an experienced mountain biker. The view of the Grand Crêt d'Eau, the Crêt de Chalam, and the Haut-Jura is also pretty good.

Very nice little walk! No particular difficulty for someone who is not sporty (haha) I would just advise against the last descent (at the end) to someone who would be afraid when it is slippery (lots of leaves and stones), in which case take the same passage as on the way there.
