The Viaduct Promenade
The route winds for 3,5 km near the villages of Molières-Cavaillac, Bez-et-Esparon, and Arre. It follows the old Tournemire (Aveyron) - Le Vigan (Gard) railway line. As it enters the mountainous terrain of the Cévennes, the walk progresses through particularly lush vegetation. This path runs alongside the large karst plateaus of the Causse de Blandas on the right bank of the Arre valley, which separates them from the granite massif of Linguas and Mont Aigoual.
Worth discovering: the remarkable Lavassac metal bridge of the Eiffel type, with a span of 80 meters and a weight of 418 tons of steel..!
