Canal de Nantes à Brest, Historic waterway in Brittany, France
The Canal de Nantes à Brest is a waterway that stretches across Brittany, running roughly 360 kilometers to connect two major cities. The route includes approximately 238 locks and many bridges that help boats navigate the changing elevations.
Construction began in the early 1800s as a major transport project linking inland areas with coastal cities. The route was officially inaugurated in 1858, establishing itself as a critical commercial passage for the region.
The waterway passes through small Breton villages where locals and visitors walk along the towpaths, and the locks remain working features of daily life rather than museum pieces.
The towpaths alongside the water are flat and accessible for walking or cycling, making it easy to explore sections of the route at your own pace. Facilities like accommodation and shops are scattered through nearby towns for visitors spending several days.
A dam built in 1930 flooded part of the original route, creating Brittany's largest lake and splitting the waterway into two distinct sections. This large body of water now interrupts the continuous path that hikers and cyclists follow.
