Day Trip Ideas

Hi all! First, I just wanted to give a HUGE shoutout to this group. It has been super helpful as I plan as I haven't been to Paris in the last five years. I'm heading to Paris this weekend to spend some time with my mother. Our trip got extended so hoping to add a day trip (or one night stay) in the countryside to the mix. We are in France for 10 days. We are pretty flexible on the destination as long as its accessible by public transit. We are open to a wide range of things - food, art, music! I looked at Auvers-sur-Oise or Giverny, but open to suggestions.
