geography

course

The Andlau rises in the Central Vosges at an altitude of 1010  m on the eastern slope of the Champ du Feu in the Forêt de la Ville de Strasbourg .

Hohwalder waterfall

It initially flows in a narrow valley in a south-easterly direction and after about one kilometer is fed by the Dreiangelbach on its right side . It now rushes westwards and shortly before Neumelkerei forms the Hohwalder waterfall ( Cascade de l'Andlau ), which is well worth seeing .

The Andlau in Andlau

After the waterfall, the valley widens noticeably. At Neumelkerei the Kaltenbaechel flows from the left and the Rohrbach a little later . It reaches Le Hohwald and is strengthened there by the Großer Breitenbach . The Andlau will now be accompanied by the Hochstraße D 425 for a longer period of time . About half a kilometer east of Le Hohwald, it takes the Luttenbaechel coming from the north on its left . Your run now leads south-east through a narrow, forested valley. At Sperberbaechel, where it reaches the stream of the same name, it turns its course to the west and is fed by the Lilsbach on its right-hand side just before the hamlet of Eftermatten . The Hasselbach flows a little further downstream . It now meanders through a wild and romantic landscape and takes on the Steinbach , Totenbach and Fischbach on its way to the village named after it .

She passes Andlau and there leaves the mountains and enters a wide plain. Your path now leads eastwards through the wine towns of Eichhoffen and Saint Pierre . It crosses under the A35 autoroute , then flows north past Stotzheim and then south past Zellwiller . It is now moving northeast through a wide agricultural area. South of the Bois de Valff , it is strengthened by the ruisseau la Scheer neuve, a branch of the Scheer . The Kirneck flows further north towards it. It flows through Hindisheim , runs south past Lipsheim , then reaches Fegersheim , where it is fed by the Scheer on its right side .

It finally flows into the Ill at a height of 143  m north of Fegersheim-Ohnheim.
