Mont-Saint-Martin (Isère) walks

A fun hike bordering on mountaineering on a very little-used route leading to the Rocher de Chalves via its southern ridge. You will discover the Ouillon, a monolith clearly visible at the foot of the ridge, before climbing an easy rock face (never exceeding 3c) along the ridge. Caution: there is a sheer drop below the ridge, so you must proceed slowly and test each hold carefully, as some boulders are ready to tumble down.

A pleasant circular through the woods of the commune of Proveyzieux leading to the Belvédère du Sialet, which offers a bird's-eye view of the Isère valley. Hikers will be happy to discover the large shopping area of Saint-Égrève, where many of them stock up on supplies.

This is a loop south of the Chartreuse, at a modest altitude. It starts at Chalais Monastery, climbs up the cable-assisted passageway of the chimney, then heads towards the small village of Mont-Saint-Martin and returns via the Cuchet route. Traditional yellow directional signs indicate the distance to be covered and the time needed to reach the destinations concerned.

A family-friendly circuit starting from Chalais Monastery and ending at the eponymous Aiguille.

This low-altitude loop takes you up an old passage equipped with ladders by hunters, before crossing the formidable Roize and returning via Chalais and its monastery.

Mount Rachais, from the hamlet of Frette, situated on its far northern side.

A well-known local walk, presenting no difficulty. It takes you to the heights of Sassenage, as well as some pleasant neighbourhoods and the village centre. The "Batteries" are a defensive structure from the "iron belt" of the late 19th century: several battery emplacements, now empty of their artillery pieces. Find out about their former function.

Easy access to Mont Rachais. View over Chartreuse, Belledonne, Grenoble and the Vercors.

Walk through the Furon Gorges leading to the top of the village, where restaurants once welcomed Grenoble residents seeking coolness on Sundays. This short walk is very popular in hot weather, as the Furon area remains cool.

In the heart of the Chartreuse mountains, the Col de Porte is a former family ski resort whose ski lifts are now closed. The paths are more or less well marked allowing you to enjoy the trails on cross-country skis or snowshoes. The proposed circuit climbs through forest, coming out on a crest and offers superb views over the entire Chartreuse mountain range.

A beautiful circular loop with no technical difficulties, allowing you to traverse a varied ridge and climb Charmant Som in the process, with views of the main peaks of Chartreuse and Belledonne.

This circular aims to offer alternatives to the very busy normal route, allowing you to discover lesser-known aspects of Chamechaude, the highest point in the Chartreuse. Without being as technical as the Arnaud breach or as exposed as the Sangle du Jardin, this route is off the beaten track: it therefore sometimes requires a sense of direction and certain (short) steep passages require effort and attention. Please read the Practical Information section carefully.

The highest point of the Chartreuse massif. As a bonus, there is a cable to access the summit platform. Magnificent panorama of the Chartreuse, with views of Mont Blanc, Mont Aiguille and the Vercors.

Circuit in Chartreuse starting from the very popular Col de Porte. The goal is the pointed summit of La Pinéa and a relaxing break at the Charmant Som chalets under the watchful eye of Chamechaude.

A very pleasant hike, described here snowshoe users, but also good for walks on sunny days.

A challenging hike that allows you to discover the most beautiful (and least known) landscapes around the summit of Chamechaude. The route includes a few fun climbs and descents, a very short off-trail section, a breach through a cliff, a spectacular couloir and an aerial sangle overlooking numerous chamois, a guaranteed spectacle for anyone aiming to reach the summit before midday. The route is far from the summer and Sunday crowds.

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).

This pretty circular starting from the Col de la Charmette allows you to climb the Charmant Som via a fairly uncrowded route (but you won't avoid the crowds at the summit...). The final climb up a chimney requires caution, but does not present any particular difficulties.

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.

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.

La Pinéa via the ridge that connects it to Charmant Som. On a clear day, there is a beautiful view of the Grande Sure, Charmant Som, Chamechaude and Mont-Aiguille.

A beautiful loop around the Grand Ratz, passing by the Roche Brune viewpoint with its breathtaking view of the Isère valley.

A magnificent, easy walk suitable for young walkers. Magnificent views and an area where you are likely to encounter mouflons and chamois! The passage through the Goulet d'Hurtières is pleasant and less frequented than the other paths leading to the Grande Sure.

This circuit runs along the Saint-Eynard ridge and offers a bird's eye view of the Grésivaudan valley and Grenoble.

From Le Sappey-en-Chartreuse, climb up to the ridges of Mont Saint-Eynard, which offer beautiful panoramic views of the Belledonne mountains, the Dent de Crolles and Chamechaude.

Easy walk on this “tooth” overlooking the Isère valley and offering an interesting view over the east foothills of Chartreuse.

This low peak and its twin opposite on the Vercors side, the Dent de Moirans, watch over the exit of the Isère as it flows quietly towards the Rhône and the entrance of rain and snow clouds pushed by the north winds. A remarkable viewpoint over the valleys, it is an ideal half-day walk.

The city has developed the western ascent of the Bastille, which is little known except to a few runners. This ascent is accessible via the Route de Clémencières. The proposed descent takes you back to the Jardin des Dauphins, but you can take another usual route (Fontaine du Lion or Porte Saint-Laurent, or even the Grenoble cable car, nicknamed "les Bulles").The slope is quite steep but safe. You will pass by some unusual views of the valley and the Grottes de Mandrin, a defensive structure of the Bastille's glacis.This hike should not be attempted in rainy weather or up to 24 hours afterwards, as the ground is slippery. The return trip is not recommended.

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

This beautiful hike on the Sornin plateau allows you to visit the large pylon overlooking the Isère valley at a place called La Dent du Loup.

Grenoble, capital of the Alps, is well known. Climbing 400 metres from the centre of the city reputed to be the flattest in France is less common. We suggest a slightly challenging walk to the military memorial on Mont Jalla and, on the way back, discovering the "380 steps".

In Vercors, discover sharp limestone pavements, wildlife and flora. Hike from La Molière towards the east via Le Sornin (medium mountain range).

A short family walk offering excellent views for the effort. Best done on a day with good visibility. Please note: a hiker has informed us that in summer, at weekends, access to the plateau is restricted: you must take a shuttle bus (or a chairlift, which is quite far away).

The perfect family walk: easy, fun, with trails that all lead to the same place, Pré Faure. This circuit is unique in that it passes through the "Désert Jean-Jacques Rousseau", worthy of the greatest romantics, climbs up to the Ferme Froussard, a historic site linked to the Resistance, and returns via a viewpoint offering a superb view of Grenoble and its valley. More challenging access from the town of Fontaine via the "Coup de Sabre"

A beautiful hike on the northern ridges of the Vercors with breathtaking views of the Isère valley.

This walk offers a multitude of additional routes to vary according to your mood!

A flower-filled, refreshing walk with panoramic views.

Starting from the Plateau de Gève, take a walk in memory of the British airmen who supplied the Maquis du Vercors resistance fighters.

This very easy circular is suitable for everyone in the following two cases:- to whet your appetite in the morning,- to aid digestion in the afternoonthis pleasant route on the wide tracks of the plateau, in the middle of the woods, offers a most enjoyable walk in all seasons.

A nice circular walk from the parking place at the Geve Plateau. There is a diversion to La Glaciere, which is a cave system, and a shorter diversion to Cabane 44, which was used by the resistance during WWII. The views from the ridge are great.

Please note that there are some fairly technical sections in the Coulou Pass, with and without handrails. Please take great care It is not possible to complete the loop; see the notices

An easy hike to discover the statue towering above Voiron. A real treat, especially in snowy weather. The statue of the Virgin Mary was erected in honour of the Iron Virgin of Le Puy-en-Velay. Legend has it that Bonnassieux committed suicide after sculpting the Virgin. However, he did not commit suicide and died with honours. He deliberately placed Jesus in her right arm so that he would not hide his mother's face as she blesses the town

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.

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.

A beautiful classic circular in Chartreuse, starting from La Correrie via Habert de Billon, Col de la Ruchère and finally Notre-Dame de Casalibus.

In the land of silence of the Grande Chartreuse Monastery, an easy and very pleasant walk in all seasons.

A very easy route on the ridge separating the Autrans valley from that of Lans en Vercors.

A diverse hike: forests, ridges, vast panoramic views...

This hike offers numerous panoramic views of the Chartreuse, Belledonne and part of the Vercors, both along the ridge trail and the pleasant path that crosses the mountain pasture.

From the hamlet of Le Truc at the north-eastern entrance to the village of Autrans, you can access La Molière mountain and discover the Isère valley and the city of Grenoble through a gap in the mountain. Higher up, you will see all the mountains surrounding Grenoble and its region. Don't look for the "pas" (step) of the bear as a paw print because, here as is often the case in the mountains, "pas" is a diminutive of "passage" (passage).
