Departure from the Burnkirch chapel south of Illfurth. Parking is available at the adjacent cemetery. A first sign explains the history of the site during the First World War. The circuit is marked by a red ring, "Circuit du Haulenwald".
(S/E) From the south-west corner of the cemetery, head to a grassy crossroads with a large cannon.
(1) Take the grassy path on the left that runs along the side of the slope until it crosses a farm track. Continue straight ahead, following the red ring (there are several other signs at the crossroads). The path runs along the edge of the woods before entering them.
Reach a farm track at the edge of the woods. Turn right, then left onto the grassy path that climbs uphill. Cross the woods until you reach a T-junction.
(2) Take the path that climbs towards a casemate twice on the right.
The path continues winding above the position, then climbs along the ridge until you reach elevation 369, at the edge of the woods.
(3) The path continues to the right, following the military boundary until you reach the start of a gully and a forest track. Continue straight ahead, climbing a track until you reach a T-junction. Turn left, and the path leads to a ridge position.
(4) The path descends along the military boundary until it leaves the woods (altitude 345).
Go around a concrete electricity pole. The path winds through fields until it descends to the Saint-Urbin Chapel. Turn right, then (at elevation 331) left and right again to climb back up to the ridge.
Enter the Buckenberg woods until you reach the Heidwiller artillery observatory.
(5) The path runs along the edge of the woods and enters the woods via a steep descent until it returns to the grassy crossroads where the large cannon is located.
(1) Retrace your steps along the same path to return to the Burnkirch Chapel (S/E).
