Promenade des Pertes de la Valserine

The Promenade des Pertes de la Valserine in Bellegarde-sur-Valserine is a short and easy walk that follows the Valserine, a river that takes its source in the Jura mountains and empties into the Rhône. Starting near the train station in the city, the path goes upstream to the Pertes (French for “losses”), where the river disappears in natural canyons dug into limestone rocks.

This page has proposals for additional exploration of the area (beyond simply walking there).
