Gravel track on the banks of the Seine

Highlight (Segment) • Other

Super pleasant towpath, except the WE because there are quickly too many people. But during the week it is a real happiness. 🤗 And for die-hards, there is even a small bumpy single in parallel. 🥰

The paths from Cormeille to Herblay have a few flights of steps but offer beautiful views overlooking the Seine and the forest.

Very pretty and pleasant until Conflans. Afterwards it's a bit sad.
Easy walk. Lots of beautiful houses.
