Called the Mastrou or Train de l'Ardèche, the Vivarais railway is a 33-kilometer-long metre-gauge tourist railway line, connecting Lamastre to Saint-Jean-de-Muzols, near Tournon-sur-Rhône. A steam train, with a locomotive classified as a Historic Monument, invites young and old to discover the green Doux valley, a preserved area with panoramas inaccessible by road. Part of the Mastrou line can also be travelled by railbike starting from Boucieu-le-Roi. Twelve kilometers of descent by railbike in the Doux gorges, with a return by historic railcar, to do as a couple, with family or with friends! trainardeche.fr velorailardeche.com

Connecting Tournon to Lamastre, 175 meters long, the bridge sees over 4,000 vehicles and about 200 heavy trucks pass each day in both directions.

The bridge called the King's Bridge was erected at the beginning of the 13th century. Indeed, in 1291, Philip the Fair officially declared the foundation of Boucieu and thus created a co-lordship with the lord Geronton de Valmordane. Boucieu le Roi was endowed with a charter of franchise (tax exemption for its inhabitants) and a bailiwick (court of justice). The charter of franchise would attract numerous merchants and notables. Access routes were therefore paramount, hence the construction of this 3-arch bridge. It would later be widened in 1773. https://www.ardeche-hermitage.com/fr/catalogue/detail/pont-du-roi-129249/

Dating from 1483, the Grand pont was built over the Doux river between Tournon sur Rhône and Saint Jean de Muzols. The arch, measuring 51m, was at the time the largest arch in the world. More than 100 years of work were necessary for the construction of this bridge.

The Gorges du Doux owe their name to the river that flows through them. The name is misleading: the river and the gorges have a wild, even tumultuous aspect! This valley will amaze you with its diversity: river, forest, relief, pastures… This exceptional space has also been classified as a sensitive natural area (Espace Naturel Sensible) since 2015. Discover different atmospheres depending on where you are! In the middle of the valley, stop in the characterful village of Boucieu le Roi and walk to the banks of the Doux river. It is hard to imagine that this modest watercourse can overflow its banks, but one must always be wary of still waters: the floods of the Doux are terrible! Besides, it is said that the name "doux" (soft) was given to moderate the relentless character of the river…
