Since 1960, a panoramic road follows the canyon up the hill through the garrigue, the common Mediterranean vegetation when arriving from the North, and ends in Saint-Martin-d'Ardèche with a view of the river flowing towards the Rhône in the direction of the (Fuji-Yama silhouette) of the 1900 m high Mont Ventoux in Provence.

The river would finally be spanned by a stone bridge built in 1895 - which would be destroyed five years later by one of the furious swellings the Ardèche was accustomed to after autumn rains, before it would be regulated and dammed in the Cévennes.
