Saint-Hilaire (Isère) walks

This is an unusual and challenging hike. It takes in all the highlights of the Dent de Crolles and its surroundings. Source du Guiers Mort, Arche à l'Aiguille, Sangle Barrère, Chemin des Crêtes, Arche de Rocheplane and Lance Sud de Malissar.

A beautiful, fairly challenging walk offering splendid views of all the peaks of the Chartreuse. Caution! Read the comments carefully. A tricky scree slope has been reported.

Short family-friendly walk with a magnificent view, manageable on foot or on snowshoes.

A pleasant hike above Grenoble, fairly short but with superb views.

This route has the least elevation gain for climbing one of the four peaks over 2,000 m in the Chartreuse. Magnificent view of the back of the Dent de Crolles, the north of the Chartreuse and, on the other side, the majestic Mont Blanc.

The "Passage de l'Aulp du Seuil" ("Aulp du Seuil" passing): this hike is one of the most beautiful hikes of the Chartreuse massif.

This is definitely the easiest and shortest way to climb the Grand Som. Caution for those prone to vertigo: between (2) and (3), the walk becomes a climb in places. The passages are often narrow and can be daunting.

To reach the Fontanieu chimney, the classic route climbs through the forest on the western slope of the Mallissard valley. It is difficult to find your way here due to a maze of forest paths created by logging. In addition, the maps are often out of date.The proposed hike avoids this wooded valley and passes through a little-used area where the route is easy to follow with very few intersections. It consists of a single track, climbing up a valley to the Col de Fontanieu. However, this adds 2 km to the hike and 50 m to the elevation gain. From the pass, the trail climbs to the foot of the cliff and follows it to reach the Fontanieu chimney. Then there is a long aerial traverse followed by a ridge crossing. From the summit of the Lance Sud de Malissard, the return is via the Col de Bellefont and the Col de la Saulce. 4/12/2023: Some sections may be closed (see practical information).

A magnificent hike that combines a natural section starting with a climb through the forest, continuing over the pleasant Pas de La Suiffière and then the easy but aerial ascent of the south ridge of the Grand Som, with a cultural section exploring the Monastère de la Grande Chartreuse, a veritable work of architectural art.

This is a short, unusual walk that follows the Alloix torrent. Curious walkers will spend more time admiring the work of the water than walking. This walk can end with a leisurely stroll through the narrow streets of the old village or, as the locals say, "on the paths of yesteryear", where local markings will guide you.

Une superbe boucle où l'on côtoie, cascades, tunnel naturel, grotte, pas d'escalade, vire aérienne, alpage avec pour couronner le tout, au long du parcours, de très beaux points de vue. Attention, ce parcours exposé n'est pas adapté aux personnes sujettes au vertige et n'ayant pas l'expérience de traversée aérienne et de pas d'escalade. A éviter impérativement par temps humide en raison des risques de glissade.

A forest loop allows you to reach the Pont de la Betta, the starting point for a multitude of other hikes, while discovering the charming hamlet of Prabert and the magnificent Cascade des Avoux waterfall.

A classic hike in the heart of Belledonne, ending at one of the great lakes of Belledonne, outside the Sept Laux. Round trip hike.

A short hike to enjoy this geological feature: a flaming fountain.
