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.

In addition to its view of Lake Coiselet, the Oliferne peak is distinguished by a strange sculpture which stands in the middle of the ruins, like a guardian watching over a castle.

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.
