Oratoire de Nère Fontaine (Saint-Pierre-d'Entremont) 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).

A beautiful, wild hike in the heart of the Chartreuse and on the edge of its nature reserve. The route starts in the woodland, to the sound of the waterfall and the source of the Guiers, climbs up the cliff face, crosses the wild and rugged Chaos de Bellefont, passes through mountain pastures, and reaches the ridge with its stunning views.

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.

This first stage of the Tour of the Ten Highest Peaks of the Chartreuse links the Col du Coq to the Col de Porte, via Chamechaude, the highest point of the Chartreuse massif. However, with the passage through the Double Arche, situated at the foot of Chamechaude, followed by the Rampe de l’Écureuil (or Pas du Lapin), and the canyon on the descent, these gems of the Chartreuse massif do require sure-footedness, combined with a good sense of direction.

Chamechaude (2,082 m) and the Dent de Crolles (2,062 m) are the two highest peaks in the Chartreuse; allow for a walk of around 30 km – fancy a go?

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.

This second stage of the Tour of the 10 Highest Peaks of the Chartreuse links the Col de Porte to St-Pierre-de-Chartreuse, via the Charmant Som and then the Grande Sûre. Whilst presenting no particular technical difficulties, this stage is nevertheless one of the longest on the Tour.

Footprints in the snow for this walk, which can be enjoyed in the summer sun or in the shade of oak and fir trees...
