So I finished this superb day in Thoirette, at the Restaurant du Pont. And frankly… what a great idea! 🍽️ A very good meal to close this day as it should be. After spending several hours on the water, the pleasure of sitting down at the table and eating well takes on another dimension!

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 small stone viaduct with 2 superimposed lanes, one for cars with 6 arches and one for the train with 11 arches. Atypical.

The bridge separates two departments, the Jura and the Ain. "Iron bridge. For several centuries, the Ain was crossed at Thoirette using a ferry, called Christouphe's ferry, named after the commune where the passenger resided. From 1808 to 1811, the riparian communes contributed to building a bridge in place of this ferry. The project had been drawn up by Mr. Cordier, from Orgelet, an engineer then in charge of directing the works for the Simplon road. Various obstacles opposed the execution of this work. It was not until 1829 that an iron bridge was built, which collapsed in 1843. The Ain department has just replaced it with an iron bridge currently open to traffic".
