In April last year I visited the Loire Valley with my family. We had some amazing food and wine and visited many château.
I highly recommend visiting as many as possible but Chateaux Villandry, Château de Chenonceau are must sees. The Villandry gardens are usually spectacular, however we were to early in the year to see them in bloom but even the intricacies of the hedges are worth seeing. The Chenonceau gardens are beautiful as well but what makes this one stand out is that the Chateau is also a bridge across the river. The history behind all the chateau in the region is incredibly interesting with Mary Queen of Scots and Catherine de Medici having lived their lives in the region.
