Redon is a small historic town full of charm. It is located at the crossroads of the western waterways with the Nantes-Brest canal, and the Channel-Ocean link. The Grand’Rue is lined with elegant half-timbered houses.

View of the Isac dam and the Nantes-Brest canal from Bout du Bois

Highlight • Viewpoint

This passage runs along several hundred meters of the dike which separates the Isac river from the Nantes-Brest canal. Always nice to see two rivers side by side.
The surroundings are very quiet and with shade if necessary.

The canal offers very beautiful walks accessible to everyone with small more technical passages such as "the single hidden" near the dike. Opposite the end of wood beach is very nice too.

A lock among others? No, because here you can have your bike repaired! This repair workshop is ideal because it is located along the Vélodyssée.

May 10, 2023,Tag 9 - Von Redon nach Nort-sur-Erdre

The tour rippled along, like the river and later the canal, always on the side. Towards the end, the rain rippled and didn't stop.
The canal doesn't just go straight, but meanders in places, has wild-looking banks and surprised me with its varied view.
