3. Jardin de Tuileries (2 hours) - Lovely gardens! This is a must see (or at least walk through). There are relaxing fountains, hedges, flowers, and an awesome Musée de l'Orangerie in the middle that features massive Monet water lilly paintings (also included in Paris Museum Pass). There are some snack stands selling sandwiches and wine throughout the park so you can really make an afternoon here. This is a nice relaxing site after the bustle of the city. You can pair this in the afternoon with a morning at Sainte-Chapelle and Notre Dame since they are all within walking distance of one another.
