In the winter, the valley is a cul-de-sac, with its road finishing at Val d'Isere. In the summer, there is a pass over to the Maurienne Valley at the head of the valley (the Col de l'Iseran), and a couple of others further down, including the Little St Bernard Pass eastwards to Italy via La Rosiere and La Thuile and the Cormet de Roselend northwards.
