Great, very long descent of almost 50km from Col de l'Iséran (2764 m) through Val d'Isere to Bourg-St-Maurice (810 m). Then climb towards Cormet de Roselend (1968 m). In Les Chapieux (1560 m) we stay overnight in a rustic mountain refuge.
Addendum to the last post: Traffic disruption at Col de la Madeleine due to the sheep drive.
