Refine your search for walks in Carency (ruisseau) - Affluent du Souchez
From Carency to Mont-Saint-Éloi via Bois Poret

A fairly classic route around Mont-Saint-Éloi (the area is very well signposted), with three less-travelled sections to Villers-au-Bois.
It's a bit winding (not intuitive, as one of my friends always says), but it allows you to take a few less-frequented paths.
