The Pont d'Arc (French pont = bridge) is a large natural bridge, located in the Ardèche département in the south of France, 5 km from the town of Vallon-Pont-d'Arc.
The arch, formed when the river Ardèche broke through a narrow escarpment between its meander, is wide and high at the top of the opening. It is a very popular canoeing and kayaking area and is heavily visited by tourists. It is usually described as the natural entrance to the Ardèche Canyon.
