the bridge is designed so that it can be flooded during floods

Pretty little bridge essential for crossing the Ibie and thus continuing your hike towards the Pont d'Arc

Dry canyoning the other way around. Just before the campsite on the Ardèche is the entrance to the river, which dries up in summer. I agree with the previous writer, this is not a safe hike in many parts, as it contains exposed areas, climbing and bouldering elements. I suspect that it is easier to go uphill along the river (like we did). Assuming you have the relevant experience, this is a fantastically beautiful and very special hike. I haven't had so much fun 'hiking' for a long time. But please be careful.

An interesting whim of nature that reveals itself to the visitor here with the "Pont d'Arc Ardèche". At the same time, this natural arch broken by the river into the rock is an impressive testimony to the power of the water that has carved its way through here over time.

Otherwise you can only see the "bridge" down from the beach, from up here you have an impression of how the natural monument has integrated into the whole landscape and how the Ardeche has dug through the landscape.

This old bridge allows you to span the Ibie. Be discreet when you arrive and you may have the opportunity to observe the many toads and frogs that you will hear as you approach the site.

From here you have a view of the Pont d'Arc, a natural arch, 54 meters high. This passage over the Ardèche was formed more than 120,000 years ago by karst erosion. The Pont d'Arc is well known to kayakers, swimmers and diving enthusiasts.
