From Meaux to Trilport via the Dhuys Aqueduct

A varied hike from station to station, following the underground Dhuys aqueduct. This route allows you to discover the Marne first, before taking forest paths and crossing pretty villages.
Along the Chalifert Canal and then the Marne d'Esbly to Thorigny

A walk along the water, first along a canal and then along the Marne. The only elevation gain is at Côte Saint-Jacques, which the canal crosses via a tunnel. The outdoor sculptures near the Dhuys footbridge add a touch of heritage.
Along the Marne from Thorigny to Noisiel

A hike dominated by water, with a long stretch along the Marne towpath and crossing two wetlands on boardwalks. After a nice touch of industrial heritage at the former Menier chocolate factory, you cross Noisiel Park on wide paths in search of some remarkable trees.
