Favourite destinations of yours for two-three days in early March, leaving from Paris

I went March 2008 to see Loire Valley Chateaux;
stay in Amboise (Leonardo Da Vinci's house is there behind the castle) or Blois.
You have to see the Chateau Chambord

Looks like a lovely area, thanks for the reply. I can see I have some research to do.

Is the Loire Valley going to be drab and colourless that time of year, or will the scenery still be beautiful despite the colder temperatures? Not expecting any flowers, of course!

Versailles or the LOire Valley, easily done by train.

Is the Loire Valley going to be drab and colourless that time

to my knowledge no place short trips from Paris are reputed as having great weather in March; but I come from Chicago and it is more green in the Loire compared to Chi at that time of year.
maybe go to the Perigord region; I went there about a month ago, lovely area not many tourists; but that is 5 hours south from Paris

Yes, sigh, I know you are right about the weather. I guess I will have to look for a cozy hotel with a fireplace so we can warm up at night!

Perigord looks like it might be more comfortable temperature-wise, but less practical for our time frame. We could fly directly further south rather than taking the Eurostar from London, but my husband has never been to Paris, and doesn't want to miss the chance to see it.

We are obviously fine with cold weather being from Ottawa but it would be nice to have a break from that.

All of the countryside is drab and colorless that time of year except where the air is dry and the sun shines through along the Riviera or the southern tip of Provence. I’ve spent many winters visiting family in different areas of France. If your husband has never been to Paris, why give it only two days. There’s enough to see and do for months and months in the City of Lights. Or, fly to Nice for the whole time you are in France if you want color and sun that time of year.
