Bassin du Flumet walks

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).

The second stage of this circular route in the Belledonne Massif, sometimes along a balcony trail, sometimes through wild valleys, takes you around the Allevard Massif. ⚠️15/06/2026: a notice indicates a rockfall at Cul de la Vieille between 2 and 3, making it impossible to follow this route. You must take the GR®738 as a detour. Please let us know in the comments if you have any information regarding the lifting of this notice.

A beautiful high-altitude lake accessible by chairlift from Prapoutel. Descent via the wilder side of the resort. Passes by Gros Caillou, a popular spot for climbers.

This is a magnificent, easy walk that takes you through many beautiful natural sites, with breathtaking views of the Grésivaudan valley and the Chartreuse mountains.

An original outing that allows you to discover the superb work carried out here for the construction of the Touvet funicular railway. The ascent is on foot and the descent, to relieve the knees, is by funicular. (Please note): This route is currently closed. See explanations here (Comment from a hiker) dated 18 June 2023: small difficult section: crossing the scree slope where you need to use two ropes to reach the path in the forest.

First stage of this lovely circular route in Belledonne, with the magnificent mountain lake, Lac Blanc, as the final backdrop.

A very beautiful stage in the Belledonne Massif, starting from the mountain pastures, which takes us through a mineral world to a setting of tranquillity on the edge of the Sept Laux (seven lakes).

Third and final day of this trip to the Chartreuse to collect the car.

The route runs mainly through the Chartreuse Natural Park, passing through the massif's iconic passes and mountains. The route combines fairly steep climbs, passages through plateaus, mountain pastures and a village.
