In reply to Removed UserRaulDuke:
It is a strenuous walk, no doubt, but on several of the 9 days we were on the route we arrived with plenty of time to relax and get well fed at the refuges. It is, in the end, just a walk, albeit one in a mountain environment with lots of ups and downs, but one on which I was happy to take my inexperienced, not terribly willing teenage kids, and not, at least in the summer, some desperate Alpine thing.
That said, when the weather turned foul on the second day, we did bail, then get back onto the trial after a night in the lowlands (Corte). Just doing that was fun too.
We did not have time, with children, to do the whole route in one go, and so elected to start at Vizzavona, where the NE/SW diagonal railway line crosses the trail, and do the more mountainous northern half.
