South to north in late September?


Posted: Sun, May 18, 2008, 20:31

I'm planning to walk the GR 20 in late Sep. I'd like to ask for some advice. Is it easier to get to Conca from Ajaccio or Bastia? And by what means? What about Calenzana at the other end? What's the nearest airport I could link it up to? Or Calvi to Nice by ferry?
Any help much appreciated.
