I may have mentioned this to you in the past, but I highly recommend the Pyrenees, its a trip I would do again one day if possible. My German biking friend and I did most of the range from east to west, very neat gradual change of elevation and look as you toodle along the range.
I arrived in Toulouse, down to Carcassone, then west following the Pyrenees on the French side until into the Basque area, where we went into Spain for a few days, then up the Atlantic coast and then to Bordeaux. I then biked alone from Bordeaux back to Toulouse for the loop and the flight back home.
You're very welcome over here valygrl. We have the famous Alps in Switzerland of course... Then there's the Pyrenees from East to West along the north coast of Spain, not a flat mile to be seen!

Thanks you guys. I'll be sure to look you up when I start planning.
