The Via Fluvia: Bourg Argental - Annonay (V73)

The Via Fluvia is fully developed downstream from Bourg Argental and winds its way through the Déome valley towards St Marcel les Annonay, then on to Boulieu les Annonay and its medieval town. It reaches the center of Annonay, passing through the heart of the historic Canson and Montgolfier paper mills. This section of the Via Fluvia is a grand journey through time, showcasing the inventions and industrial expertise of the capital of northern Ardèche (suspension bridges, the first hot air balloon flights, Canson paper, etc.).
