Parc du Petit Prince walks

For a long time, the Thur was used as a dumping ground for the dye works in the Thann-Cernay valley and beyond, as far as Ensisheim, for chlorides from the potash mines.Today, these industries have disappeared, which is regrettable, but the polluted ditch has regained its wild beauty and the trout have returned. Starting from the Ensisheim Pond, this route offers a tour of the river, its tributary the Old Thur and its forest, the Thurwald. Please note: Japaneseknotweed invades the banks of the Thur every year, obstructing the view of the river between May and November.It is best to do this hike between November and early May.
