From the Romanesque town of Rosheim via Rosenwiller, set off to discover the Ehn valley. The route takes you through this beautiful little corner of Alsace, with the village-manufacture of Klingenthal and the wine village of Ottrott at the foot of Mont Sainte-Odile! On the way back, you can simply take the Voie Verte "Portes Bonheur, chemin des carrières" to the starting point.
