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

There is a monument there commemorating the local resistance fighters, who used this meadow to parachute in equipment for the British secret services during the Second World War.

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.

From the ruins of Oliferne Castle, perched on a rocky spur in the Jura Mountains, you can enjoy breathtaking views of the Ain Valley and beyond. Once a medieval fortress, its ruined walls and towers now blend into the rugged landscape. Its strategic position allowed it to control access to the region, making it a must-see when hiking the Pic d'Oliferne.
