Treffort walks

This is a hike that starts with a ferry crossing. The objective is to take the two elegant bridges. The first bridge crosses the Drac. The second bridge crosses the Ebron. Satisfactory markings.

This walk is a variation on the classic tour of the Himalayan footbridges of Lake Monteynard, which does not require a boat trip (for a fee) to return to the starting point. In addition, this route takes you to the Pas du Berlioz (very beautiful view of the lake) and the Pont de Brion. It is hardly any longer than taking the boat, as you don't need to go all the way to the pier, which is quite far away. However, part of the route is a return trip.

A magnificent hike 35 km from Grenoble, with no difficulty, offering 360° views of the surrounding mountains. The climb to this summit is a magnificent hike through the mountain pastures (one of the largest in the region).

The highest point in the Vercors at 2341 m, the Grand Veymont offers 360° panoramic views.

A vertiginous and rarely-taken loop, where you come across ibexes and chamois at every hairpin bend. Make sure you always have a helmet (ibexes love to send stones flying), as well as crampons and an ice axe until late in the season, as névés remain in place fairly long within the steep Serre-Brion couloir. It is best to start your hike early in the morning so that snow is still hard when reaching this couloir.

A hike that visits one of the 7 Wonders of Dauphiné.

This superb ship, isolated from the main Vercors mountain range, remains docked and admired by all, especially its majestic bow, which dominates the villages of Trézanne and Richardière.

A pleasantly varied loop between vegetation and rock, spiced up by the crossing of a scree slope and a passage with cables at Pas du Fouillet. To be done outside the snowy season.Return facing the imposing block formed by Mont Aiguille. CAUTION! The scree slope and Pas du Fouillet between points (3) and (5) are currently closed (July 2025). At point (3), continue straight ahead to reach the Pas des Bachassons via the Serres and Maupas ravines, point (6), from where you can reach the Cabane des Aiguillettes, point (6), for a picnic. Then, you will need to return to the Pas des Bachassons to continue the hike.

Follow the legend of the Pierre Percée (Pierced Rock) on this short circuit that will take you to one of the seven wonders of the Dauphiné.

The Piquet de Nantes (2,215 m) and the Tabor (2,389 m) near La Mure in Isère are the two highest peaks in the Tabor massif and can be reached separately, but the route proposed here connects the two peaks via a trail that gives an almost high-mountain feel while being easy and very pleasant. It takes only an hour and offers a circuit with beautiful views of the Matheysine lakes and the surrounding mountains.

Although located within a ski resort, this circular route avoids deforested and lunar landscapes as much as possible. The ascent is mostly through forest on little-used tracks. The crossing of the north-west ridge is superb, culminating in the magnificent Arche de la Fenêtre. The aerial descent of the east ridge leads to the Col des Deux Sœurs.The return journey to the Pas de l'Œil is via a little-used path that continues along the foot of the Gerbier ridges. Via the Combe Charbonnière, the route joins theGR®®91, which takes you back to the Balcon de Villard.

A remarkable family walk in the southern part of the Hauts Plateaux du Vercors Nature Reserve. Vast lawns on the plateau and views of the Trièves and Mont Aiguille, the foothills of the Oisans and the Dévoluy.

A hike in Drôme and Isère, but starting from the Vercors drômois side. The Vallon de Combau and the Tête Chevalière at 1951m. A panoramic view over the Trièves valley. During the months of May and June, the Vallon du Combau is must-visit destination, where you can enjoy the flora and fauna, particularly marmottes. A relatively easy hike up to the Pas de l'Essaure pass, then a little more difficult.

Climb from the very pretty spot called Les Clots towards the Col Vert and descend via the Combe Charbonnière, a scree slope that is a little tricky to navigate. View of the Belledonne massif from the Col. This allows you to get a good view of the Vercors landscapes and enjoy the variety of the mid-mountain terrain. Not to be attempted in winter! Between 6 and 7, there is a high risk of avalanches, especially towards the Combe de la Charbonnière.

A long hike across the Vercors Highlands ("Hauts Plateaux du Vercors"), to reach the Grand Veymont. Breath-taking view of the entire Vercors massif and Mont Aiguille.

A walk of discovery from Vercors in a loop between the cliffs, forest and meadow. Small height change.

This easily accessed summit is located on a ridge between the "Vallée de la Gresse" and the Vercors plateau. It offers a breathtaking view on Belledonne, Les Rousses and a bit further Les Ecrins.

A lovely little hike that allows you to easily explore the Cirque d'Archiane. Discovering this place is magical as it is surrounded by magnificent cliffs. You are bound to come across a couple of griffon vultures nesting in the crevices of the rock and gliding over the cliffs.

This is a lovely little hike, with a trail that takes you to the middle of a cliff overlooking the Bournillon cirque 400 metres below, offering magnificent views of the Bourne gorges. This route allows you to discover the springs of the Moulin Marquis, the Grotte des Gaulois and the Porte du Diable, a natural limestone arch. The total elevation gain for this hike is around 200 metres.

Ascent of the Petit and Grand Taillefer, the first peaks of the Belledonne range, clearly visible from the city of Grenoble. The view from the summit is magnificent, taking in Mont Blanc, the peaks of the Écrins Massif (Barre des Écrins, Roc de la Muzelle, etc.) as well as the Aiguilles d'Arves to the east and the peaks of the Vercors and Dévoluy to the west.

A hike in the heart of nature on the outskirts of Grenoble. The trail takes you through woods to Lac Archard, where you can enjoy a leisurely stroll. Then, in a more open area, the path climbs up to the Robert Lakes.
