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.

Located in Saint-Germain-de-Joux, the Marmites de Géant (Giant's Cauldrons) were carved by the Semine river and its tributary the Combet. Gigantic cylindrical hollows, two to three meters deep, are connected by a few successive waterfalls.

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.

This boundary stone marked the border between Franche-Comté (north) and French Bugey (south). To the east, the Pays de Gex was separated by the Sardinian Corridor, in which the Spanish Way was located.

Extraordinary panorama, ideal place for a break on the GTJ route, a picnic or even a stopover in a gîte (booking: https://refugelaconay.clubalpinbourgenbresse.fr/reservation/)

The Col de Bérentin connects the Valserine Valley to the Retord Plateau, passing through the beautiful Jura forests. Its ascent is gradual and the road is little traveled.
