In reply to PTatts:
Alta Via 2? About 150km long, glacial section can be bypassed. One very short section of via ferrata where some of my party did clip on, but it's no more than a scramble. Almost no one clipped the other sections. Helmet recommended for one section though, there were a lot of loose stones being kicked down, though if you waited for a five minute gap you'd be okay.
If you skip any of it, skip the final Southern quarter, and don't miss staying overnight at Piz Boe.
