Lac de Saint-André (Les Marches) walks

This walk combines a variety of points of interest, starting from Les Éléphants, Chambéry’s iconic monument, before heading towards the Charmettes neighbourhood, dear to Jean-Jacques Rousseau. Further up lies the Grande Montagne, which, whilst nothing like high mountains, nevertheless offers panoramic views of distant mountain ranges. The first section follows theGR®96route.

Day2 of this trip via the Col de Bellefont to reach the Dent de Crolles plateau.Descent via the pass above the Trou du Glaz, then down to the Col des Ayes and up the Roc d’Arguille to the Col de Pravouta and the hut of the same name. ⚠️ 27/11/2025: Route modified following a rockfall. It is no longer possible to take the path via the Trou du Glaz (5). The area remains particularly dangerous due to the high risk of further rockfall and falling boulders. Following this incident, the municipality of Saint-Pierre de Chartreuse has issued a by-law to close several hiking trails (for walking, snowshoeing and ski touring). For an ascent of the Dent de Crolles, it is possible to take the route via the Pas de l’Oeille. You can also go via the Guiers waterfalls to reach (E).
