As soon as it leaves Le Cheylard, the cycle route changes its scenery: the Dolce Via, with the Eyrieux as its main thread, now runs into the steep valleys of the Boutières.
If today the route can be travelled by bike without effort, imagine for a moment the construction of the railway at the end of the 19th century, which is the result of a real technological feat due to the nature of the terrain. The last vestiges of this extraordinary railway past, the viaducts, tunnels, bridges and trenches, all carved out with the strength of your wrist, accompany you to Saint-Agrève. A colourful and easy walk.
