From Rothau to Natzwiller

Follow the road for 4 km until you get to Natzwiller (half way, you can go to the Charapont farmhouse restaurant, on the right, follow signs to  NEUVILLER LA R. >  ). Continue through Natzwiller, going straight ahead (follow Rue Principale keeping to the left) for 800 m as far as a sharp bend towards the left. Don't follow the bend, but go straight ahead into Rue de la Hautte-Goutte. After 150 m, you cross a bridge over the stream, La Serva.
