In reply to sam_owen41:
We did Alta Via 2 back in 2003. There was not that much via ferrata, and nothing that really warranted getting harnesses on, except for one move depending on your nervousness. We loved the Sella Ronda, and would highly recommend going to up Piz Boe (as I recall, it's not on the route, but we ended up there because the lower rifugio was full). 4th section wasn't as good. We didn't do the Marmolada. Took a day out at one point to do a couple of via ferrata.
Overall, it was brilliant, and I would recommend it to anyone....
