Beautiful hike but some paths are not easy to find. I have the impression that some paths are not used enough to remain visible.

What is to be remembered from this route is the passage through the Carnelle forest. However, there are too many roads on the Isle Adam and along the Oise. No particular difficulty.

Always a pleasure to go through this pond, having a corner of water allows you to look away from the ravito and to stop. The pond is an inescapable point, the proof of each outing I pass by.
