Soon you'll reach the stairs, part of the Le Rhône dépasse les bornes: sentier des douanes (The Rhône River goes too far: the customs path) educational trail. Along the route, information panels with QR codes reveal the fascinating history of this former customs path. These historic stone steps follow an old border crossing used by customs officers, merchants and travellers during the 17th and 18th centuries. They later served as an escape route for Huguenot refugees travelling to Geneva and, during the Second World War, for people crossing the border in search of safety. The staircase also descends the Rhône's ancient fluvio-glacial terraces, carved by the river over thousands of years.
