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! 😁

Beautiful. Be careful, the path is actually a scree: steep and not very stable. Doing it in the direction of the descent is difficult or even problematic, it is better to continue climbing the scree (to the top!!).
