The Authie at Maintenay

The Authie is a river in France that runs in the Hauts-de-France region and, especially in the lower reaches, also marks the border between these two regions over longer stretches. It rises in the border area of ​​the two municipalities of Coigneux and Souastre at a height of about 122 meters and generally drains north-west through predominantly agricultural areas. The valley of the river is home to a diverse flora and fauna, but also passes many places with historic castles and monasteries. In the last twelve kilometers of the river forms an estuary , located between the towns of Fort-Mahon-Plage and Berck for Bay Baie de l'Authie expands where the Authie finally to a total length of 108 kilometers in the English Channel opens. On its way, the river crosses the Somme and Pas-de-Calais departments .
