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

Highlight • Other

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.

End of our vacation. A 420km family trip. Nice weather along the canal. The landscape is still just as natural. Nice average. 😅 3rd puncture for me. 40km for Coco, re-record. Toto equal to himself: it drives hard without ever complaining. He started again after a good fall. Well done tribe!

Leaving Nantes by bike is completely hassle-free, but getting to the canal gets a bit tricky. But finally sailing on the Nantes-Brest canal is beautiful, lonely and uncomplicated. We are at a small campsite in the middle of nowhere.
