Departure from Saint-Colomban-des-Villards (Savoie)
L’Ouillon, at the summit of the Sybelles ski area, offers a magnificent 360° view of the Alpine massifs. The ascent via the Col du Glandon and the descent via the Col de la Croix de Fer allow you to explore the mountain pastures in the area. As this circular route is fairly short, it can be usefully extended with a visit to the Potron and Guichard Lakes to enjoy the reflections of the peaks spotted from the Ouillon.

Difficult
Departure from Besse (Isère) (Isère)
Return to the Romanche by heading down the Ferrand valley.
A return trip – though optional – to the Quirlies glacial lake would be a shame to miss.

Departure from La Ferrière (Isère) (Isère)
A classic, well-known hike in the area to explore the Lacs des 7 Laux. Here, only the descent is described and used to complete this traverse, as it is not possible to continue easily on to the Refuge de l’Oule.

The second stage of this circular route in the Belledonne Massif, sometimes along a balcony trail, sometimes through wild valleys, takes you around the Allevard Massif.

From the Oule refuge to the Chalet du Bout via the Col Morétan and the Aup Bernard
8.43 mi
+4,075 ft
-5,548 ft
8 hrs
Very difficult
Departure from Pinsot (Isère)
This long route will take you up and down two mountain passes (Morétan and Vay), through the Morétan Lakes valley, and across the wild, unmarked foothills leading to the Col du Vay. You’ll then begin a long, dizzying descent along a balcony path between the Chalet du Vay and l’Aup Bernard, finally arriving – after one last rather steep climb – at a very pretty spot in the middle of which stands the Chalet du Bout, the perfect place to spend the night.
Please note: this hike involves crossing two snowfields as well as a steep, exposed descent.

7h 45
Very difficult
Departure from La Ferrière (Isère) (Isère)
A very physically demanding day, with very steep slopes right from the start that give you almost no respite until you reach the refuge. But from the Refuge de la Grande Valloire onwards, the views are magnificent.

Moderate
Departure from Oz (Isère)
A downhill hike through a rocky landscape where you hop from lake to lake – yes, it’s possible.
Of course, you’ll need to take the cable cars of the Alpe d’Huez–Vaujany ski area to reach the summit of the Dôme des Petites Rousses, the starting point of this hike.
Please note: the time estimated by the software is an underestimate.
