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! 😁
