47,26 km cycling route from Conflans-Sainte-Honorine to Mantes-la-Jolie

The Seine à Vélo leaves behind the old Seine boatmen’s capital, heading for Mantes-la-Jolie, with its impressive riverside collegiate church. Nature begins to make its presence felt as you cycle west along the Seine’s meanders, past islands. Make a short detour to Poissy, a town with a rich architectural heritage, influences going from 13th-century French king St Louis to modernist architect Le Corbusier and his Villa Savoye. Next, don’t miss the Parc du Peuple de l’Herbe, with 113 hectares of nature to discover. Continue to the Ile de Loisirs du Val de Seine at Verneuil-sur-Seine. This Leisure Island provides an ideal stop for relaxing by the water, enjoying many outdoor activities, including, in warmer weather, swimming.
Gradually, the urban atmosphere gives way to the rural, and to bucolic landscapes. The Vexin area now welcomes you…

The route

On this stage, some stretches are specially set up for cyclists, while others are on roads shared with motorized traffic. At time of writing, certain portions are only provisional, with parts on earth or grassy tracks. There are works that need to be carried out between the bridge at Triel-sur-Seine and the RD113 road at the level of Mézières-sur-Seine.

For the time being, the existing provisional stretches force you to leave the side of the Seine for a few kilometres at a time in several places.

The necessary works will be carried out bit by bit. Remember to download the GPX tracks to help you find your way in the meantime.

Don’t miss

  • Musée de la Batellerie et des Voies Navigables at Conflans-Sainte-Honorine: Looking down on the old town, the Château du Prieuré is home to the Musée de la Batellerie et des Voies Navigables, containing a collection of boat parts and models retracing the whole history of river navigation in France. The tour is playful as well as educational, revealing so much about life for those who worked on the country’s rivers.
  • Villa Savoye – Le Corbusier at Poissy: Part of a UNESCO World Heritage Site dedicated to the buildings of architect Le Corbusier, the Villa Savoye is one of his masterpieces. This is in fact considered a major work in architectural history, illustrating the five fundamental principles of Le Corbusier’s Modernist Movement: reinforced concrete pillars (pilotis), a roof garden, open plan interiors (avoiding supporting walls), free façades and horizontal strip windows.
  • Parc du Peuple de l’Herbe at Carrières-sous-Poissy: Dedicated to preserving biodiversity, and insects in particular, the Parc du Peuple de l’Herbe offers walks, leisure activities and discoveries. In the heart of its 113 hectares of nature, the Maison des Insectes allows visitors to observe living insects in several vivariums, plus there’s a butterfly house.
