Chris Jeggo had a great time touring the Pyrenees in September, and has now put his photos on to Flickr:
No accommodation was booked in advance, which caused no problems, but which enabled the itinerary to be adapted to the weather. This varied between seriously sunny and seriously wet.  
He’s thinking of doing something similar next year, probably a two-week tour to include Mont Ventoux, the Grand Canyon du Verdon and the southern Alps.  Let him know if you might be interested in joining him.
