If you go even further west from Geneva, you will be in the Champagne region with its fields and hills in just a few minutes. The route begins at the edge of this region, in Chancy on the border with France. The small town lies on the Geneva-Lyon trade route and has always been an important border and transit point. Chancy is agricultural, like all the villages in this fertile landscape. The first part of the hike takes you along the Rhone. It winds on a narrow path through a natural, unspoilt area to the famous border stone no. 1, which marks the westernmost point of the country.

Continuing along the French-Swiss border, past historical milestones, the route climbs through the Chancy forest on a listed path of national importance. Nearby, traces of Roman times have been found, such as the remains of a brickyard with a kiln. The route then leads down into the Vallon du Longet, where the river is crossed on a 45-metre-long wooden footbridge. The path dives into a canopy of leaves. After climbing back up the valley, the next river follows further on: the Laire, which has remained very natural. Near the river and the shooting range of Les Raclerets, there is a picnic area with a fireplace and southern flair: the ideal place for a break before continuing through the agricultural fields.

The rest of the route mostly consists of historic transport roads with a different atmosphere: leaving the forest, you cross through a hilly, picturesque landscape. The path is lined with avenues of oaks, typical of the canton of Geneva. You pass the village of Avusy with its castle, Champlong. Finally, the path returns to the Rhone with a beautiful view of the Jura and the Vuache, before it ends back in Chancy.
