Beautiful, simple, easy walk; lots of traffic noise on the "road" section, a bit of a shame, but the color of the water is magical

Unfortunately I was unlucky with the weather, but even as I drove past the place looked very nice, lots of grass and a place to swim.

The Chemin des Fècles offers a superb route. As you follow this path which passes from deep woods to steep cliffs, be extremely careful not to go too far to the edge of the void. Above all, respect the safety instructions.
