Atypical and unmissable village in the Entremont valley, Saint-Pierre-d'Entremont has the particularity of being on the border between Savoie and Isère. The Guiers river marks the separation between the two departments but also two villages with the same name: Saint-Pierre-d'Entremont (Isère) and Saint-Pierre-d'Entremont (Savoie).
