These beautiful cliffs you see here are the Donzère gorge. This natural site is not a gorge strictly speaking, in the sense that only one of the banks, in this case the left, has a very steep slope plunging directly into the river. This remains impressive, because the cliffs are high.

The Pont d'Arc is a natural arch in the south of the Ardèche. The structure is at least 500,000 years old and its dimensions are impressive: 54 meters high and 60 meters wide. The water gradually penetrated the limestone rock and eventually created a huge opening to the Gorges de l'Ardèche.
