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.

Sucé-sur-Erdre marina

Highlight • Structure

Pleasant body of water bordered by a few restaurants and cafes. Ideal for a picnic or a break with your feet in the water. For swimming, find out because the water can be bad.

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.
