An old path, abandoned for decades, redesigned as a downhill run with a smooth feel! Yes, I know, it's not the Alps! 😀🏞️ Watch out for any pedestrians...

This is where the Somme River rises. Its name is traced back to Celtic origins and also gives its name to the department of the same name. At the time when Gaul was part of the Roman Empire, the river was called the Samara. It ends its approximately 245-kilometer-long river life in the Baie de Somme, where it flows into the English Channel.

Magnificent walk along the water, then visit the underground canal along the canal in a path between the trees with holes, bumps and bends (a real treat) to finish with a nice route in the Holnon woods. I recommend it. To do either as a walk or at speed, the choice is yours!
