The bridge separates two departments, the Jura and the Ain. "Iron bridge. For several centuries, the Ain was crossed at Thoirette by means of a ferry, known as the bac de Christouphe, the name of the commune where the passenger resided. From 1808 to 1811, the riparian communes clubbed together to build a bridge in place of this ferry. The project had been drawn up by Mr. Cordier, of Orgelet, an engineer then in charge of the direction of the Simplon road works. Various obstacles opposed the execution of this work. It was only in 1829 that an iron bridge was built, which collapsed in 1843. The department of Ain has just replaced it with an iron bridge currently open to traffic". Statistique de la France - 1855 - Ministère de l'Agriculture par Imprimerie Impériale à Paris - p53.

A café in the small village of Thierette. It is a very beautiful place next to the Ain river. It's just over the river and a nice place to take a break.

Hidden in the moss-covered woods, this magical cave is a sight to behold. Although it is no longer permitted to enter the cave, its entrance is spectacular. Inside the cave there are submerged sections that have been explored by divers.

Starting from the hamlet of Bombois on the left bank of the Ain valley, a family walk in the forest leads to this waterfall with its funny name. Find "8 walks around water" in a booklet on sale for €2 at the Tourist Office
