Gravel-Mountains bike tour: les Casemates

From the Soufflenheim cemetery in the direction of Koenigsbruck, after the basin, take the forest road that runs at an angle. After 1 km, look out for the Soufflenheim shelter on your left. Continue for 200 metres and take the downward path which leads you into the "Donau" forest. Continue along the path until you reach a crossroads with a carriage road. Turn left, continue for 300 metres and turn right towards Leutenheim. At the foot of the Heidenbuckel hill, turn left to reach the Heidenbuckel shelter. Turn around to find the path that will take you past the Heidenbuckel on your left. After passing the Heidenbuckel, take the first path on your left and follow it for a few kilometres until you reach the D163 on your left. Continue on the road for about 1 km, then turn left onto the forest road of Donauberg. After 7.5 km, look out for the silhouette of a new concrete giant on your left, which stands almost at the edge of the road, yet is well camouflaged. Continue on your way for about 200 metres, then turn right and continue on this road until you reach the D37. Turn right and follow the road for 500 metres, then turn left and take the forest path called Deieslach for 250 metres, then turn right. Continue on the path until it joins a new main forestry road called "Allée de l'Eichelgarten", turn right and follow this for about 400 metres to the forestry road on your left. Once again, take the path to the junction of a main forest road called "Allée de Haslach" to turn left. Observe at the corner of these 2 paths, a concrete structure which was used to protect and hide an armed soldier to defend the Koenigsbruck casemate which will be on your left after about 250 metres. Continue along the Allée de Haslach. When you arrive at an important crossroads, continue on the right to pass ponds, vestiges of the extraction of clay by the potters of Soufflenheim. At the end of the clay field, at another crossroads, turn left and continue on this road until you reach the D344. On this stretch you will pass 2 pillboxes both with heavy machine gun battlements covering the forest road called "Allée de Deieslach". When you reach the D344, the main road from Soufflenheim to Betschdorf, turn left onto the forest road for 300 metres, then take the first forest road on your right. Follow this road until it crosses a forest road. Turn left and continue for 200 metres to turn right. After a few moments, you will pass an old shooting range, the remains of a barracks. After this vestige, follow small paths on the right to go along the forest. When you reach the cemetery, follow a small path along the enclosure which leads to the D37 and the starting point.
