Water in all its forms. During this excursion, you will travel around Lake Vioreau by following the small stream that flows into the lake.

The small stream feeding the Canal de Nantes à Brest contains many remarkable engineering wonders. By following it, you will go on a magnificent journey through the little-known heritage of the picturesque and historical region of the Loire Atlantique.

It connects Lake Voireau and its dam to the Canal de Nantes à Brest. During its construction, to ensure a constant slope of 14cm per km, while crossing the various valleys existing between Vioreau and the canal, it was necessary to build 4 aqueducts (known as Arcades) and a long 600m tunnel to avoid following the twists and turns of the contour lines.

Remarkable sites: 
Vioreau pond
