The way to get there is essentially on the road but it is almost deserted and the view of the gorges is sublime.

The path that leads to the ichthyosaur fossil goes back up into this beautiful ravine, following a stream which flows among pubescent oaks.

In the hollow of a canyon that splits the rock, the road opens up spectacularly in the heart of the mountain along a bubbling river. Gorgeous !

The passage in the canyon as in the photos is not very long, but the whole road is great.

Super nice trail! The upper part is very rolling up to the ruined construction. Afterwards the slope gets steeper for a few hundred meters and the very stony ground (typical of the region) requires finesse to pass on the bike. At worst it's on foot. Then it ends with a beautiful section in the undergrowth, without much difficulty. It is a GR so itinerary of Rando, beware of walkers! Part of the marked circuit n°12 from Entrepierres.
