There's not much to add to Flavio's comments. The difficulty is at most C, mostly more like B/C. The supposedly easy via ferrata is often exposed and has a beautiful route. There's also a walking section in the middle, which isn't too long and begins with a ridge walk. I was pleasantly surprised by the new via ferrata, even though in my opinion it has too many rungs at times, or requires too frequent clipping and unclipping. There's also a steep suspension ladder towards the end. In any case, I like this via ferrata much better than the lower Val del Ri, which strikes me as more of a gym than a gym.
