Idyllically situated at the end of the Lützeltal.

While the prosperous times in the town of Lucelle are over, the Lac de Lucelle is a nature reserve that captivates with its peace, idyll and beauty. The lake can be easily walked around on a well-developed nature trail, and there are many benches where you can watch the ducks and fish in the lake.

The Etang de la Gruère nature reserve is a paradise for nature lovers. Opt for a morning hike to enjoy the calm, and to observe the rising mists over the water.

The Source du Doubs is a powerful karst spring in a heavily karstified area of the Jura Mountains. It is located near Mouthe, in the Haut-Jura Regional Nature Park, at an altitude of 937 m at the foot of the wooded, up to 1419 m high Mont Risoux mountain range, which marks the border between France and Switzerland. The Doubs rises from a cave in the rock from a small, approximately five-meter-deep spring basin. The spring discharges an average of 1740 litres per second and is the exit of a complex cave system with several siphons. The discharge can vary greatly. Several layers of rock can be distinguished on the rock above the spring. Below the spring, the river plunges down over a small waterfall. About two kilometers below the Source du Doubs, the approximately nine-kilometer-long Cébriot flows into the Doubs.

Imposing grotto and at the same time a place of pilgrimage. Here you should switch from the hiking trail near the bridge to the road and pause for a moment and enjoy the gentle coolness and refresh yourself with the water from the Karlsquelle (which is said to have healing powers). A small karst spring arises inside the cave. The water flows as a trickle from a stalagmite into a shallow basin. There is a crucifix under the entrance arch of the grotto, dedicated to Saint Columba of Sens, a 3rd century martyr. The place has been the destination of a pilgrimage on August 15th since the 13th century. The spring water is said to have miraculous healing powers.

The Plain-de-Saigne pond is a small artificial lake located in Montfaucon. It's a great place to picnic and admire the reflections of the sky and trees on the water. You can also learn about the history of the lake, which was once home to a mill and peat extraction site.

Grotto in the rock with many thank you plaques.
