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.

Historic centre of Malestroit

Highlight • Historical Site

Thanks to its half-timbered houses, its stone facades and its sculptures, Malestroit is labeled “city of character”.

A thousand-year-old village, Malestroit still houses houses from the 15th and 16th centuries as well as locks, mills and churches full of stories.
