re: You have four days in Paris - what do you do?

We love to visit Notre Dame but haven’t been since the fire. Sacre’ Coeur is also amazing. The views of the city alone are worth a visit. Saint Germain has some great food. I remember the Gregorie but there a so many. Museums are also worth visiting, we loved Musee d’Orsay. Also fun to just walk and find something unexpected.

Lots of great day trips using railroads. We visited Reims in Champagne region.
