Aubette (rivière) - Affluent de la Seine walks

A hike that’s half urban, half woodland. A pleasant route that climbs through the woods below the neighbourhoods of La Grand-Mare, Les Sapins and Le Châtelet in Bihorel. The descent takes you via La Petite Bouverie and Le Longpaon de Darnétal, mainly through the woods.

This marked GR® route around the Île-de-France region (with a few forays into neighbouring departments and regions) complements its "little brother", the GR®1, by forming a circular route around Paris, generally with a slightly larger radius. It follows the same overall pattern: first, a radial section starting from Paris (more precisely from the Pont d'Austerlitz, near the former confluence of the Bièvre and the Seine), going up the entire Bièvre valley, then continuing to Villiers-Saint-Frédéric, in the Yvelines. From there, it is a circular route that loops around the Île-de-France region, close to its borders with neighbouring regions. The route passes through beautiful regions, often untouched by intensive urbanisation, regional nature parks and other protected natural areas, and takes in some architectural wonders.

Seventh stage of the Grand Tour of Île-de-France on the GR®11, starting from the village of Genainville, in the heart of the French Vexin, and heading towards Chars station further east. This stage goes hand in hand with the previous Mantes-Genainville stage, with a night in Genainville or the surrounding area necessary to walk between Mantes and Chars stations. This beautiful stage continues the crossing of the equally magnificent French Vexin Regional Nature Park, heading generally eastwards. It joins andthen climbs up the Aubette de Magny valley, crosses a series of agricultural plateaus between Oise and Val d'Oise before descending into the Viosne valley to reach Chars.
