Departure from Saint-Pierre-de-Chartreuse (Isère)
This is a loop trail that passes through the Grand Som and, to avoid the crowds, descends along the Arête de la Suiffière (a little exposed but easy), then joins the Col de Freney (and the forest) and, via a path with numerous hairpin bends, returns just above La Correrie, our starting point.

Departure from Saint-Christophe-sur-Guiers (Isère)
This easy hike in summer becomes more difficult with the onset of winter conditions. A few centimetres of snow are enough to cover the markings on the ground and make it harder to progress on the steeper sections.
This hike can be done in half a day from mid-November onwards, but don't set off after 2pm, otherwise you'll need a head torch for the return journey.

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).

Departure from Crolles (Isère)
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.
