Park in the free car park on Quai Maurice Berteaux, in Le Pecq.
(S/E) Head north to cross the Seine via the Georges Pompidou Bridge.
(1) Turn right immediately after the bridge, onto Quai de l'Orme de Sully and then Boulevard de la Libération. Follow the right bank of the Seine, following theGR®2route.
(2) Leave Rue Max Gauffreteau on your left and continue straight ahead along the towpath. Walk alongside the Seine on your right and the water treatment facilities on your left for a good while.
(3) The towpath continues along Quai de l'Écluse. As you pass, note the very exclusive British School of Paris, a little corner of England in Croissy. Finally, pass under the Pont du Maréchal Delattre de Tassigny.
(4) About twenty metres after the bridge, turn left into the park. Walk straight through the park, then turn left to join the road leading to the bridge, near a roundabout. Then turn immediately left onto Rue des Ponts. Cross the Seine in two stages, passing over the Île de la Chaussée.
(5) At the end of the bridge, go down the steps on the right. Walk along the Seine with it on your right and the D113 on your left (a noisy stretch due to traffic).
(6) About 900m after the bridge, you’ll reach the site of the Marly Pumping Station, which supplied water to the Palace of Versailles (see the photo and the “During the walk” section for a bit of history). Continue along the Seine.
(7) After passing the "Buffallo Grill" restaurant, take the towpath on the right (you’ll immediately appreciate the peace and quiet). Follow this path to Les Pyramides (the tennis temple) and cross a car park.
(8) Continue along a tarmac “road” beside the Seine, which leads back to the starting car park (S/E).
