Cycle path along the Canal Somme

The canal follows the course of the River Somme and is a combination of a side canal and a canalised river. Construction work had already begun in 1770, but was not completed until 1843. It was intended to connect St. Quentin with the English Channel for freight traffic. However, economic use has been in decline for many decades, but like many canals in France, tourist use by pleasure craft and houseboats is increasing. (Wikipedia)
Like most canals in France, this one is also made accessible by accompanying cycle paths. A relaxed, sometimes also meditative cycling, because there is not so much variety. But also absolutely beautiful landscapes on the unregulated Somme lined with castles and mansions delight cyclists again and again
