Departure from Miribel-les-Échelles (Isère)
Set off to explore the geological features in the forest above Miribel-les-Échelles, heading towards the Col des Mille Martyrs. Numerous crosses, some recent, others ancient and steeped in history, mark this route. In other open areas, you’ll enjoy panoramic views of the Chartreuse mountains and the plain stretching towards Les Échelles and Saint-Laurent-du-Pont. To avoid roads as much as possible, you’ll take certain paths deep within the forest that aren’t always shown on the IGN map.

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).
