A week in France - what pairs best with Paris?

We’re a couple planning a first week in France and know Paris takes a few days, but we’re unsure what to add - the chateaux of the Loire, a couple of days in Provence, or the Riviera. For those who’ve done a week, what pairs best with Paris without too much time on trains?

The Loire Valley is a great choice with Paris for a week. It’s not too far from Paris, and you get a completely different feel with the châteaux, small towns and countryside.

After several days in Paris we did the easy train from Paris to Loire Valley then rented a car. We stayed a night each in Blois, Chinon and Amboise. So much to see and lovely dining/wine!
