Hi there:
My wife and I are flying into CDG on April 6, leaving there on 19th. We visited Paris many times, also saw Chamonix, Nice, Nimes, and Cassis--great places. This time we'll pick up a rental car at the airport and first go to Loire valley for 5 days--already booked Castle Fiori. Then we'd like to explore another area. We love architecture, art museums, and lots of hiking--either in city or natural areas. It would be great if we could go on an arc of sorts--coming back to CDG on a different route. Prefer to limit driving to ~ 2-3 hours on most days. Should we do Breon-Normandy-Paris, Dordone-Lyon-Paris, or may be Provance-Burgundy-Paris? Any suggestions are greatly appreciated.
