レ・アリエスの天然記念物・トップ8

The Areuse karst spring is a natural spring which emerges from limestone rocks and forms the Areuse river. You can start your hike from the village of Noiraigue and go up the river to the source, located at the foot of the Clusette cliffs. Along the way, you will enjoy views of gorges, bridges and waterfalls. The Areuse karst source is a good example of underground water circulation in a karst system.

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 journey of the Areuse river begins here. After more than 30 kilometers, the Areuse flows into Lake Neuchâtel – also a pretty destination.

At 1,302 meters above sea level, Mont Châteleu offers a superb panorama of the Jura massif. You access by a beautiful path in the middle of a fir forest which culminates on a fairly clear summit.

The Areuse rises directly from the mountain, a very beautiful place.

Very nice place at the karst source of the Orbe. Easy to relax.
