Located between the districts of Paris-La Défense and Nanterre, the Parc du Chemin-de-l'Ile gives pride of place to water. Its filtering basins, fed by the Seine, are omnipresent. The site also has the appearance of a landscaped park. The regular, mineral shapes of the basins gradually give way to meadows, to the winding banks of the counter-ditch, to isolated trees and hedges of various species. This park was designed so that visitors can relax in a place made up of lawns, pontoons by the water, large meadows where fauna and flora evolve without constraint, filtering basins, aquatic gardens, as well as family gardens. Children are not forgotten with three play areas.

On the Île de Chatou, the Maison Fournaise is a former riverside inn and hotel. It now houses a restaurant. In 1880, Renoir wrote, "It is the prettiest place in the vicinity of Paris." Renoir painted about thirty canvases in Chatou. The most famous painting is Luncheon of the Boating Party, which was painted from the restaurant's balcony. Next door, the municipal museum houses collections on the history of the site and of boating, one of the first modern leisure activities on the water.
