The Port du Gros Caillou stretches over some 600 metres alongside the river Seine, between the Invalides and Alma bridges. A pedestrian area, it forms part of the Left Bank’s leisure walkway known as the Parc Rives de Seine. As well as enjoying views of the Grand Palais and the Eiffel Tower, walkers can discover the Fluctuart, an urban arts centre set up in a barge, and the Archipel des Berges de Seine Niki de Saint-Phalle gardens, a set of floating gardens created on five moored barges.
