Walk along the Seine where the Impressionists painted

I haven't tried the app Ma Rando which is mentioned in the article, but it might be of use elsewhere in France. Perhaps I should say "eventually of use", since when I searched for the GR65 I found almost nothing related to that route.

This article highlights a new 130k hike which I find fascinating, but will probably never get opportunity to walk. When I was in Paris I chose to visit the Musee d'Orsay instead of the Louve as I'd heard it had more of the Impressionists' paintings on display. Spending time in both would have been overwhelming for me.
A few days later we visited Monet's home and gardens in Giverny; a lovely place. I remember being surprised at his large personal collection of Japanese paintings; so extremely different than his own style.
EDIT...I just did a google search and Monet had a collection of 231 Japanese block prints; many on the walls of his home.
