The disappearances of the Valserine

An easy walk along the river banks from the town centre to the place known as "Les Pertes de la Valserine", where the river disappears into a bottomless pit, before reappearing beyond a labyrinth of limestone canyons.
Valserine is the first french river certified "rivière sauvage" or wild river. It guarantees a water of highest purity and has lent its name to our destination.
Trouts and grayling spawn there and reserves in some stretches of the river protect them.
