Riking G15
The GR® 15 is a beautiful discovery close to the Marne with riverside cafes, vineyards, battles, its enchanting setting which inspires writers and artists.

The GR® 15 long-distance hiking trail connects the south of Paris, specifically from its starting point at the Maisons-Alfort metro station to its destination, the Château-Thierry train station in the Aisne department, following the many bends of the Marne River.
It thus crosses eastern Île-de-France: Bonneuil-sur-Marne, Bry-sur-Marne, Clayes-Souilly, Lagny, Meaux, La Ferté-sous-Jouarre, Nogent-l'Artaud, and finally Château-Thierry. Numerous train stations are located along the route, allowing hikers to customize their stages as they wish.
