The Pont d'Arc is a natural limestone arch spanning approximately 60 metres across the Ardèche river at the entrance to the Gorges de l'Ardèche, in the Ardèche department of Auvergne-Rhône-Alpes, France. It is one of the largest natural arches in Europe and the most prominent natural landmark in the region. The arch was formed over thousands of years by river erosion, as the Ardèche gradually cut through a meander loop to create a shortcut through the limestone headland. Today the river flows under the arch in both its natural course and, in summer, through the swimming and canoeing corridor that passes directly beneath the opening. The arch rises approximately 34 metres above the river surface at its apex. The most photographed angle is from the D290 road-side viewpoint on the north bank, which frames the arch against the gorge cliffs behind it. The easiest access is a 10-minute walk from the designated car parks on the D290, which lead to a river-level viewing area and a designated swimming zone. Canoeists paddling the gorge pass directly under the arch as the first major feature of the downstream journey. The adjacent Caverne du Pont d'Arc — a full-scale replica of the Grotte Chauvet, one of the world's oldest decorated caves with paintings dating to 36,000 years ago — is located 3 km west of the arch near Vallon-Pont-d'Arc and is a UNESCO World Heritage Site in its own right.
