In Paris you can go to the spot of Joinville-le-Pont, accessible with the RER A, it is easy to go there. You will be able to enjoy a nice paddle ride on the Polangis canal in the middle of nature. For a more urban ride, it is also possible to paddle on the Seine just outside Paris, to the south-west. This is the spot in Boulogne-Billancourt, which offers you a nice ride around the Ile de Seguin and the Ile Saint-Germain.
