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 lovely unpaved greenway. From Moret-sur-Loin, for 15 km, the surface is a little rough. 10 km before Nemours, the track has been resurfaced and is a nice, smooth gravel. We passed through without any problems on gravel bikes with a baby trailer. Our friends passed through on city bikes with a trailer. I'm including a photo to give you an idea of the surface.
