A really nice ferrata, sort of a small Jubilaumsgrat with a lot more protection and less exposure. I completed it in 2.5h but almost never clipped into the cable. Return to the cable car took 1.5h by the easy way from the col just before Großer Daumen.
This is a well protected ferrata of the easier kind, but takes 2 1/2 - 4 hrs to Großer Daumen. Depending on whether you use protection or not. Done on a very hot summer day: beware sunburn, sun continuously shining form the right. Due to the wind you don't feel it until it's too late ;-)
