Very steep descent, technically easy path (you can walk normally) but impressive for people sensitive to heights. There are switchbacks on a slope probably at least 45°. Falling is prohibited! Take this aspect into account before embarking on this hike, depending on the participants

Warning: This section is very technical for about fifteen meters. There are metal ladders, bars, and lifelines. Experience in climbing or via ferrata is required for safety. Personally, there were three of us with rucksacks weighing 10, 12, and 15 kilos respectively, and we had to make three round trips, carrying each bag together (one holding it from above, the other from below). With a fair amount of experience, this was accomplished without any problems, but we had to take our time and reassure one of us, for whom the section was particularly technical. We did it downhill and in very light rain, which didn't help. It took us about 20/30 minutes for our three return trips. Very technical descent, probably easier ascent. → Photos for illustration purposes only, not contractual.

Magnificent viewpoint, both at the top and at the bottom. Some technical sections favor hiking rather than trail running. You'll find ibexes (and their babies), chamois, and marmots at the summit. This is one of the trails worthy of a Windows wallpaper! 👌 If you do a full tour, there are some sections that are close to climbing, so be warned. However, it's possible to turn around everywhere, with plenty of side sections, so there are always solutions! 😁

As you climb up to the Col de l'Alpe, you will find a summit cross dating from the early 20th century. Erected in 1926, it was built to commemorate local climbers and hikers who lost their lives in the Alps.

This superb passage is located in the foothills of the South Granier. Technically easy, it requires concentration to be completed without difficulty.

Located between Mont Granier and Le Pinet at an altitude of 1,533 meters, this pretty green pass is located above pleasant mountain pastures which inspired its name.
