So this is not an old railway line at all. It is an aqueduct that supplies the city of Paris with drinking water. It is the aqueduct de la Vanne! Edit: the title of the unmissable has been changed by Komoot, and it has got its real name back :)

The former fortress and picturesque medieval town of Moret-sur-Loing lies on the edge of the Fontainebleau Forest and the peacefully flowing Loing River. This postcard-perfect town is indeed extremely photogenic. The most beautiful views are from the old bridge or from the right bank of the Loing.

A striking contrast in the quality of the road or the developments of the Briard Canal are painful to see compared to those of the Orléans Canal.
