Grande Sure walks

A magnificent loop starting from the Chalet de la Charmette, via the Col de la Grande Vache and Col de la Petite Vache. An aerial walk with breathtaking views.

An unmissable walk near Grenoble. Despite the crowds during these last beautiful days of autumn, we were able to avoid the rush (except on the climb to the summit).

A fairly easy route to reach this summit in the Chartreuse mountains. However, the final ascent requires a bit of energy. At Col de la Sure, you can enjoy a peaceful stroll through the mountain pastures.

Another way to reach the summit of the Grande Sure. Most hikers from the Grenoble area access it via Proveysieux and the Col de la Charmette. For those coming from the Savoyard hinterland, access via Saint-Laurent-du-Pont and the Chartreuse de Curière is an interesting alternative. From the start at (5), the route is not very busy.

A challenging day hike but very accessible for regular hikers, with varied terrain including scree slopes, cow pastures, forests and chasms, plus superb views of the Isère valley and the Chartreuse mountains.

Randonnée en huit partant des Trois Fontaines, un lieu baigné de fraicheur où il fait bon s'attarder en plein été.Le sentier commence dans la forêt en s'élevant dans une rude pente par de nombreux lacets. Il franchit des gradins rocheux pour rejoindre une bergerie d'alpage, le Chalet de Jusson. En haut de la prairie se présente la Cheminée de Jusson qui s'escalade sans difficulté pour parvenir au sommet et profiter d'un magnifique panorama. Descendre la crête et une partie du vallon de l'Hérétang puis remonter la Combe des Veaux pour retrouver le Chalet de Jusson. La descente par le Pas des Rochers de Pierre Taillée s'effectuant sur une sente en déshérence puis dans la forêt pour retrouver le parking conviendra aux randonneurs en quête de lieu secret. GPS ou application Visorando recommandé.Ce parcours s'adresse à des randonneurs bien préparés physiquement.

A varied but relatively long route up to the Grande Sure, favouring sections that are slightly steeper but above all wilder and less frequented than the usual routes: Pas de la Biche and Crête des Charmilles.

Magnificent view of the Chartreuse and the plain from the summit of the Grande Sure. The first part, from the car park to the summit of the Grande Sure, is the most difficult with scree. The descent from the summit to the Col de la Vache must be undertaken with caution. The rest is easier. The return after the Col d'Hurtières is through the woods.

This circular walk is a variation on route no. 107635379, the Grande Sure, a return walk from Saint-Laurent-du-Pont. The ascent to the summit of the Grande Sure is the same, but this route differs in its return leg, which starts from the Col de la Sure, from where the path leads to the Col des Charmilles, descends the opposite slope, then crosses the Rochers des Agneaux before hurtling down a steep cirque and joining the Route Forestière de la Charmette, which leads to the magnificent Chartreuse de Currière. This route offers the advantage of a different return journey with a similar elevation gain, despite being 2.8 km longer, but has the disadvantage of ending on a road.

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.
