The walk begins with a very varied section of the GRP® "la Seine impressionniste", starting with the imposing ESA Ariane rocket factory and its loading dock, a charming marina, the Île de loisir du Val de Seine, and several very large ponds. It continues through Triel-sur-Seine, with its pleasant Parc Senet and the architecturally intricate St Martin’s Church. The walk through the Bois d’Hautil along easy yet unspoilt paths is well worth the detour for its chestnut forests dotted with a few fine oaks, and punctuated by a large number of sinkholes resulting from the collapse of underground quarries. And we finish off gently, admiring the confluence of the Oise and the Seine. ⚠️ User comment on 18 May 2026:>Please note: at point 8, the path is closed in both directions due to reported risks of collapse; instead, take the GR®2 further down to cross from east to west
