On the Allevard side, the Grand Charnier is the Belledones peak that must absolutely be added to your list of conquests. At 2,561 metres, it offers 360° views of all the peaks of the two Savoie departments and Isère. Here I suggest the shortest route to reach it, but ‘shorter’ means steeper, and is best suited to experienced hikers. A pleasant hike with a significant elevation gain that becomes technical over the final 300 metres; this summit sometimes remains snow-covered until the end of June.

Departure from Saint-Bernard (Isère) (Isère)
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).
