Waterfalls, canyons and turbulent rapids – take a moment to stop and marvel at the power and beauty of nature. Truly awe-inspiring!


The Pertes de la Valserine canyon was shaped by the pristine waters of the Valserine River – a fine example of the power of nature. A marked footpath takes you along the banks, offering magnificent views of the gorge.

Watch the mountain stream disappear into mysterious giant’s kettles

Downstream, the river has carved deep gorges into the limestone rock, giving way to surprising bottlenecks and awe-inspiring natural formations. Don’t miss: Devil’s Bridge (Pont du Diable), Stone Bridge (Pont des Pierres) and, finally, the Pertes de la Valserine. This is where the river ends up, diving deep into the giant’s kettles carved into this enormous slab of limestone before disappearing altogether…

A fishing paradise, preserved by the Wild Rivers program

With the highest range of the Jura Mountains offering protection, the Valserine River was the first in France to be preserved under the Wild Rivers label. This means that the quality of the water and the wealth and diversity of its fish populations are recognised and protected. In particular, the Valserine River is renowned for its population of brown river trout. This natural playground is off the beaten track and a favourite spot among fishing enthusiasts.
