Parking is available near the Lion Gate, on Avenue Clémenceau.
(S/E) Take the greenway parallel to this avenue and then continue straight ahead.
(1) After passing under the bridge on the road connecting Rosheim to Boersch, you will see a section of railway track overgrown with vegetation.
(2) Pass the Boersch industrial estate and you will come out onto Rue des Jardins. At this point, the greenway is interrupted due to roadworks. Continue to the end of this street to reach Route d'Obernai, which you take on your left. After 100 metres, you will rejoin the greenway on your right and continue straight ahead. The path gradually climbs and curves sharply to the right, where you will see the hillsides of Obernai with Mont National.
(3) In the undergrowth, you will walk alongside the Léonardsau estate park. Continue straight ahead and then take a curve to the left.
(4) You will arrive in Ottrott on Chemin des Aulnes, which you will take on your left. This path is marked with a red triangle. 50 metres further on, turn right onto Sentier de l'Ehn to cross the river. Continue to follow the red triangle markings and after one kilometre, turn left to cross the Ehn again. Climb a slight slope on a tarmac road until you reach the greenway junction: take this again, on the right.
(5) Keep right, going in the opposite direction, and follow the same route as on the way there until you reach Boersch.
(6) You will come out onto the Obernai road again. Turn right onto it. Cross the Chatel roundabout and continue straight ahead on a road with a housing estate on your right and the business park on your left. This road is marked with a red triangle and leads to a dirt track, which you should follow.
(7) Cross the D216, the road linking Boersch and Bischoffsheim, and continue to follow the red triangle signs. You are now on a hillside overlooking the Rosheim valley. Ignore the two paths on your left and continue straight ahead.
(8) Just before a telephone pylon, leave the path and go down the slope on the left, walking alongside the vineyard on your left until you reach a trail. This trail leads to a path marked with a blue ring. Take this path on your left to descend to Rosheim. Turn right onto Rue des Prunelles. About 50 metres further on, turn left onto Rue de l'Abattoir.
(9) Cross the Rosenmeer stream, which has an old traditional wash house on its banks. Continue until you reach Rue de la Marne. Turn right. This street runs alongside the circular centre of the old town with its two fortified gates, including the one known as the "school" gate, which you will pass on your left when you cross Rue du Général de Gaulle. At this point, turn into Rue du Lion and continue straight ahead. You will see the Porte du Lion gate on the south side. Go through it to return to the starting point (S/E).
