If you only get round to a dip in one of Paris’ 35 swimming pools, make it this one. The Piscine Joséphine Baker is the city’s only floating pool, moored alongside the radically renovated Rive-Gauche. Festooned with bunting, the Baker pool is open to the sky in the heat of summer, when it becomes the focal point for the latest slice of Paris Plage action.
