The Valdostan Pennine Alps include giants such as Dent d'Hérens (4,174 m) and Mont Vélan (3,734 m), visible from Valtournenche and Valpelline. These summits mark the border with Switzerland and dominate landscapes of hanging glaciers, limestone faces and deep valleys. Alta Via 1 crosses this sector between Cuney, Fenêtre de Tsan and passes toward Valpelline.

Geologie
Dolomitic limestone, Penninic marbles and ophiolites characterise slopes with strong altitudinal gradient. Hanging glaciers of Vélan and Dent d'Hérens are sensitive indicators of climate change. Contacts between crystalline basement and sedimentary cover are visible along Alta Via 1 passes.
Geschichte und alpine Kultur
Dent d'Hérens was among the last great summits of the Western Alps to be climbed (1863). Mont Vélan marked for centuries the ducal border between Savoy and Aosta Valley. Historic huts such as Oratorio di Cuney testify to devotion and alpine transhumance.
Wege und Routen
Alta Via 1 crosses Fenêtre de Tsan, Col Terray and Colle di Valcournera in sections graded EE. Rifugio Oratorio di Cuney is an iconic stage. Exceptional views of Matterhorn, Monte Rosa and Grand Combin on clear days.
