Hi all, I have just read Wapping's link and enjoyed it.
I ought to chuck in my 2p's worth now I guess.
Firstly there are many, many great roads in rural France and because the second world war didn't ruin the historic buildings, they are certainly worth putting in your route planner.
Andorra is a worthwhile stop-over, we normally stay in Soldeu, the accomodation is the Hotel Bruxelles, a small apparently family run hotel. We normally ditch the bikes for a day and stop us drinking too early in the day, we go up to the top of the adjoining mountain which has a 9 hole golf course and try our hand on the golf driving range (which incidentally is adjacent to a mountain bike course and if your aim is poor, the poor cyclists have to dodge the occasional wayward ball..and our aim is always terrible..lol) then we try a little putting, but I have to say I have more luck lying on the green and using the putter like a snooker cue.....
After leaving, yes the N260 is incredible, it you should remember it can be ridden from the Med coast almost across the bottom of the Pyrenees.
The Millau bridge is worth seeing too, but go in daylight, went over it once at night and didn't really know we had done it....doh.
However, also try the Alps, the numerous Swiss passes and of course the Italian Dolomites and the great Grossglockner......
Miles and miles of good roads to ride, and don't make any excuses, get over and ride them....
