Hi Mat, your right - that is the area.
You would be fine keeping up, I didn't race round too much
Lots of places to explore and loads of small islands, all worth a visit.
I have been in winter time, last year I was there. The temperature ranged from 12 degrees in the morning to 23 on the warmest day. Sunny the whole time and the sea ranged from flat to mildly exciting.
I will be there this winter for a couple of weeks and probably re-visit some of what I did. Also planning on checking out some places I've not been to.
Next year I may do a lap of Corsica and I also want to cross over to Italy mainland and perhaps Sicily as well.
