This great route takes you through the northern part of the Ardeche. From the town Saint-Laurent-Du-Pape it runs north to Lamastre and St-Félicien. Near Lalouvesc has been a big forestfire a few years ago. The route continues southeast. Slightly north of St-Agrève is the location of the source of the rivier Eyrieux. It is not possible to follow the first few kilometres of this river, but after the town Intres the road sticks to the river. The route follows this river all the way down to the starting point of this route. The river runs only a few kilomtres further and ends in the Rhone near the town Beauchastel.
