I asked the following question to an AI, here's its answer.
For a pedestrian, is it an offense to walk on the left side of a towpath or a greenway?
This is a great question about sharing space on these paths.
On a Greenway:
The greenway is defined in the Highway Code as a "road exclusively reserved for non-motorized vehicles, pedestrians, and horse riders" (Art. R110-2).
In the absence of specific signage or lane separation, the default traffic rule applies, which is to keep to the right (as on a road).
However, as a pedestrian, if the greenway is considered a roadway where general rules apply, the Highway Code states that when there is no usable shoulder or designated area, pedestrians must stay near the left edge of the roadway (outside urban areas) to see vehicles (bikes, scooters, etc. on a greenway) coming toward them (unless it compromises their safety).
In practice, on a greenway, the goal is coexistence and sharing. Cyclists are encouraged to ride on the right, and out of courtesy and safety, pedestrians are often advised to walk on the left to face other users (mainly bikes) coming in the opposite direction, making crossings easier.
Is it an offense? It’s hard to call walking on the left on a greenway a clear-cut offense for a pedestrian, especially since the aim is to ensure their safety against other users. The Highway Code mainly emphasizes the need to use designated areas when they exist and, if not, to take necessary precautions.
On a Towpath:
Towpaths have often been converted into greenways or rural paths open to soft mobility. Their exact legal status may depend on the managing authority (often Voies Navigables de France - VNF) and local regulations.
Generally, they are treated like greenways or shared paths where the same principles of caution and sharing apply.
The same logic of walking on the left to see cyclists coming is often considered the safest for pedestrians.
Conclusion:
Pedestrians are strongly advised to walk on the left on a greenway or towpath when it’s not strictly reserved for pedestrians and other non-motorized vehicles (bikes, etc.) are using it, in order to see users coming toward them and avoid surprises from behind.
It’s unlikely this would constitute an offense punishable by a fine, especially since this practice is often seen as the best for pedestrian safety, following the logic of the Highway Code for pedestrians on roads without sidewalks. The key on these paths is caution and sharing among users.
