One day
Start on the Île de la Cité for Notre-Dame and the flower market, walk the quays past the Louvre to the Tuileries, and cross to the Musée d'Orsay for a focused hit of Impressionists. Follow the river west in the afternoon and finish at the Eiffel Tower — from the Trocadéro side, or the Pont de Bir-Hakeim — as it lights up at dusk.
