My wife and I will be in Paris for a week this May and were considering taking a day trip to one of the chateaux in the Loire Valley. I have already been to Cenonceau (but wouldn't be against going again), but was wondering what are the best ways to get out there? Also, what would be considered the 'best' ones to see?
Are good bus tours operated and if so which ones should we look into? Can we take the train there, or is it a bit inconvenient?
Would a day trip to Chartres be better/easier from Paris?
