This glacial lake backed by limestone cliffs is sometimes sapphire and sometimes emerald in color - Alexandre Dumas wrote in his book Impression de voyage in 1834: “This pretty little sapphire blue lake set like a jewel, which nature fears to lose. »

Moulin de Vulvoz Waterfall

Highlight • Waterfall

It is not a simple waterfall.
Its interest, compared to the many waterfalls in the region, lies in the hole that has been dug in the rock over time.
So you can see the flowing waters of the Vulva flowing into the void, passing through this hole.

Church of Saint-Hymetière

Highlight • Religious Site

Built in the middle of the 11th century on a priory founded in the 6th century by a certain Ymeterius, a hermit from Saint-Claude, this church is isolated in the fields (the medieval village which surrounded it was burned down in 1477 and the dwellings were rebuilt away). This gives an incredible charm to this elegant building which was completely rehabilitated in 2011. Saint-Hymetière offers a fine example of rural monastic churches from the first Romanesque age. However, it is distinguished by its vaulted nave from the outset, semi-circular and unstructured.

The bridge separates two departments, the Jura and the Ain. "Iron bridge. For several centuries, the Ain was crossed at Thoirette by means of a ferry, known as the bac de Christouphe, the name of the commune where the passenger resided. From 1808 to 1811, the riparian communes clubbed together to build a bridge in place of this ferry. The project had been drawn up by Mr. Cordier, of Orgelet, an engineer then in charge of the direction of the Simplon road works. Various obstacles opposed the execution of this work. It was only in 1829 that an iron bridge was built, which collapsed in 1843. The department of Ain has just replaced it with an iron bridge currently open to traffic". Statistique de la France - 1855 - Ministère de l'Agriculture par Imprimerie Impériale à Paris - p53.

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

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.
