The 3.5 km route passes through the villages of Molières-Cavaillac, Bez-et-Esparon and Arre. The route follows the old Tournemire (Aveyron) - Le Vigan (Gard) railroad line.
As it winds its way through the mountainous terrain of the Cévennes, the walk progresses through particularly lush vegetation. The route follows the great karstic 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.

You'll enjoy privileged vantage points over the Bez, Brun and Rognes vents and the Calles caves. The Viaduct walk also offers splendid views over the Cevennes valley of the Rivière d'Arre, dominated by the Rocher d'Esparon.

Don't miss the remarkable Eiffel-style metal bridge at Lavassac, with its 80-meter span and weight of 418 tons of steel...!
