About
Trail Walking of 12.4 km to be discovered at Hauts-de-France, Somme, Irles. This trail is proposed by temmichel.
Description
L’Ancre prend sa source officiellement sur le territoire de la commune de Miraumont, mais en réalité, compte tenu du relief, les premiers écoulements proviendraient du nord de Irles et de Pys au niveau de Ligny-Tilloy dans le Pasde-Calais. Longue de 38 km, l’Ancre est un cours d’eau de première catégorie. La vallée de l’Ancre a été utilisée au 19e siècle pour la construction de la ligne ferroviaire Amiens-Arras sur la voie
ferrée Paris-Lille (comme la vallée de la Somme entre Amiens et Corbie). L’Ancre traverse vingt-et-une communes.
Bonne randonnée en Somme
