(S/E) From Hamel Town Hall, follow Rue André Hallé south-west and take the first left onto Rue du Petit Pont.
(1) Turn left and follow (east-south-east) the wide Chemin des Marais (marked ‘Le Lanchoy’ on the IGN map at maximum zoom), signposted in yellow.
(2) It is recommended that you leave this wide track to walk as close as possible to the pond. Further on, leave the ponds behind to join the Chemin de la Rivière du Moulin a little further north.
(3) Turn right (east) onto the track. This leads to the Moulin d’Arleux.
(4) Return via the same route as on the way there.
