(Wikipedia) The Ardèche (Occitan: Ardecha) is a 125 km long river in south-central France, a right-bank tributary of the Rhône River. Its source is in the Massif Central, near the village of Astet. It flows into the Rhône near Pont-Saint-Esprit, north-west of Orange. The river gives its name to the Ardèche département of France.

The valley of the Ardèche is very scenic, in particular a 30km section known as the Ardèche Gorges. The walls of the river here are limestone cliffs up to 300m high. A kayak and camping trip down the gorge is not technically difficult and hugely popular in the summer, so much so that the control of numbers is becoming a headache for park authorities. The most famous feature is a natural 60m stone arch spanning the river simply known as Pont d’Arc (arch bridge).
