Le Doux
Highlight • Other
This valley will amaze you with its diversity: river, forest, relief, pastures … This exceptional area has also been classified as a Sensitive Natural Area since 2015.
Discover different atmospheres depending on where you are! In the middle of the valley, stop in the charming 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! Moreover, it is said that the name "doux" (soft) was given to moderate the relentless character of the river …

Grand Pont de Tournon-sur-Rhône
Highlight • Bridge
It is an exceptional work, of national interest due to the span of its formidable 49.2 m semicircular arch, a technical record for the time (in France it is comparable to the arches of "La Vieille Brioude" and Nyons ). Its aesthetics are also remarkable (observe it from the railway line, both upstream and downstream).
