With your back to Lorentzen Castle, turn left on to the D919. At the roundabout, take the cycle path on your right. In Diemeringen, turn right at the restaurant and pass the station. Before the crossroads, take the street on the right and pass under the railway bridge.
After the roundabout, turn left towards Mackwiller. Stop and visit the Roman remains. Pass through the village and take the D96 towards Thal-Drulingen.
After 2 km, at a slight incline, take the dirt path on the left and follow it to Rexingen. When you arrive in the village, turn left and make your way down the main street to the junction with the D9.
Be very careful when crossing it! Take the path which climbs up the hill. At the top, continue straight ahead and follow the forest to Adamswiller.
Turn left before the church. Follow the path through the fields to the forest road. Turn left at the large pear tree. The path continues downwards with the forest on the left and the pastures on the right.
At a wooden bench, take the forest path on your left. Follow it to the first houses in Tieffenbach and continue straight ahead.
Pass through the village. Continue for about 2 km on the D919 using the cycle path.
When you arrive in the village of Frohmuhl, turn right at the restaurant "Au Lavoir". Follow signs to the "Maison de l'eau et de la rivière" (MER). Continue on this path to the MER.
