really nice guided tour of the underground mill, also in German; it is unique and cannot be found anywhere else.

The underground mills of Col-des-Roches are a set of mills and underground tunnels built in the 17th century to harness the power of an underground river. A point of interest on your route and perhaps an opportunity to take a break and buy tickets for later.

If you're looking for a fun break from your run in the Swiss Jura, you can visit the Grotte de l'Ours, near Ponts-de-Martel. This is not a deep cave, but rather a large rock formation with several holes that you can explore. The cave is located in a beautiful little gorge, the Combe Poëta, and the path leading there is already an attraction in itself. You can admire the forest, streams and peat bogs all along the way.

If you are looking for a great adventure in the Swiss Jura, why not visit the Glacière de Monlési, the largest natural ice cave in Switzerland? You can access it on foot from the Col des Sagnettes, on the road between Fleurier and La Brévine. The cave is a karst sinkhole that contains three shafts, leading to a large ice-filled room. You can explore the icy wonders of this underground world, like stalagmites and ice stalactites. But be careful, it is very dangerous to go over the ladder or walk on the ice without the proper equipment and guidance. The Glacière de Monlési is a protected nature reserve and a unique geological phenomenon.

The Col-des-Roches Underground Mills are a set of mills and underground tunnels built in the 17th century to harness the power of an underground river. You can learn the history and mechanics of this ingenious system through an audio guide or guided tour, and marvel at the sight of the waterwheels and sawmill in action. The temperature inside the caves is constantly 7°C, so don't forget to bring a warm jacket. You can also visit the museum which presents the role and function of mills and hydraulics in the region. The underground mills of Col-des-Roches are a fascinating example of the ingenuity and creativity of man in harmony with nature.

A remarkable waterfall for the Jura. The grotto, however, is a little cave at best 😃

The cave of the Grande Cave is a special cavity for the piece of history to which it bears witness. On several occasions, during the warlike episode of the Ten Years' War (1634-1644), the inhabitants in exile took refuge in the woods and the caves lost in the mountains, including the Grande Cave. Today, the cellar is accessible to the public. Note, however, that a cable attached to the wall allows you to travel the last 100 meters.
