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.

L'Isac dam on the Nantes-Brest canal

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.

Lock 11 — La Prée

Highlight • Structure

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.
