The Gorges du Guiers Vif (or Gorges du Frou) is a canyon located in Isère and Savoie between the towns of Corbel and Saint-Christophe-sur-Guiers, and having as tributary the Guiers Vif.[1]
In 1994 a little road was built that directly connects Saint-Pierre-d'Entremont in Savoie to Corbel. It passes through the Gorges du Guiers Vif. However, for driving people, it is reserved to the residents.
