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.

Feed channel

Highlight • Other

"The feed channel or" Small Canal "with a length of 21.3 km connects the Vioreau reservoir to the Nantes-Brest Canal. It allows the water supply to the first section of the Canal to compensate for the drop in level due locks and evaporation. Its construction - 1833 to 1836 - is a technical masterpiece, a slope of only 14 cm / km, four aqueducts, a 600 m underground passage, many small picturesque stone bridges, washhouses ... "
From a cycling point of view, the path that runs along the canal is most of the time a simple single, in places grassy. Suitable for gravel and therefore mountain biking. On the other hand, I would not do the section between the Pas d'Héric and the Patis Blondin with children, the path passing near the water on numerous occasions. On foot, no worries.

Port Mulon Park and Castle

Highlight • Castle

19th century castle overlooking a large 15 hectare park, known for its rare species and for its music festival "La Nuit de l'Erdre". The path along the Erdre can be very muddy in winter. Beyond the place called Les Mares Noires you can continue on a single track that crosses a fairly densely wooded area and/or the more rolling Noe-Guy path.

Very rolling path, a little monotonous

Chemin du Pas Chevalier

Highlight • Trail

A more direct alternative in terms of time and kilometers than the EV1 to reach Sucé from the Canal. Still, more gravel/mountain bike than touring with panniers in my opinion.
