Park in the car park at the top of Hohrodberg, located along the Linge road, just after the Aqua-Viva hotel.
(S/E) Take the path (welcome sign) going up to the left towards the Glasborn farmhouse inn. The entrance to the path is a German blockhouse (sign no. 1).
The path crosses the western slope of the Kleinkopf and Barrenkopf halfway up, passing through the "No Man's Land", an area between the two front lines. After about 100 metres, you will see the German trench on your right under the edge of the woods (sign no. 2).
When you reach the Glasborn farmhouse and inn, take the access road for about 20 metres to join the path that branches off to the left towards the Col du Wettstein. From here, you will enter the French lines, where the trenches and ground movements caused by the war are still clearly visible. By taking the designated path, you will be able to visit the first French fortifications on the small ridge (elevation 941) overlooking the Glasborn farmhouse and inn.
(1) Leaving the small ridge, turn left and follow the path towards the base of the Hurlin (elevation 939). Turn left.
(2) You will arrive at a second rocky ridge, at elevation 941, parallel to the first, located 300 m behind you.
Leaving this second ridge, turn left and follow the path along the side of the Hurlin slope (sign no. 5). Go around a wooded hillock (elevation 938) to reach the Col du Wettstein and the National Necropolis.
(3) The circuit continues around the cemetery on the left.
(4) Find a forest path that branches off to the right of the road (follow "Centre de vacances le Vallon", Anneau Jaune). Pass the Madelon spring. At the Y-junction that follows, turn right and, after a few dozen metres, take the path that climbs steeply to the right at a right angle. At the top of the hill, leave the forest and return to the D11 road. Turn left towards the Glasborn farmhouse inn.
(5) You will pass the memorial to the Battle of Linge.
Take the road that leads to the Glasborn farmhouse inn. After a few dozen metres, at a Y-junction, take the path that climbs between two barbed wire fences towards Schratzmaennele, later called Schratz by French soldiers. You will reach the infamous glacis of La Courtine. Shortly after entering the Schratz pine forest, take the path on the right to reach the crossroads of the La Courtine paths.
:5:: Now retrace your steps for a few metres and turn right (north) onto the wide path that crosses the western slope of the Schratz halfway up (signpost no. 9).
After 200 metres of climbing straight ahead, you will arrive at the German trenches (signpost no. 10).
At this bend in the path, take the ridge trail on the left that descends towards the Linge Memorial Museum. Before arriving at the museum and crossing the D11, you will reach the monument to Commanders Colardelle and Barberot (sign no. 12).
Cross the road and the car park to reach the Memorial (you can visit the museum and the German trenches) and then the viewpoint.
(7) From the museum, to reach the German cemetery at Baerenstall, take the path that descends to the east of the museum. It joins a forest path below the D11 road. A little further on, on the heights to the right, you will see the shelter of the Bavarian command post from 1916-1917. The forest path leads to the pass and the German cemetery at Baerenstall.
(8) Turn left, cross the rest area and climb the steep path that leads to the top of Schratzmaennele (signpost no. 13). At the top, turn left and head towards the quarries, following the path that roughly follows the line of the first German line.
After about 30 metres, a sign (No. 15) indicates the location of the large quarry. Take the small access path that leads you inside the quarry. Then go back up the same path and turn left. A few dozen metres further on, you will arrive at the fort (sign no. 16). A few metres further on to the left, there is another structure (sign no. 17) which is more spacious and can be visited in complete safety.
(9) The latter overlooks the small quarry that you will discover via the path descending to the left. Leaving the small quarry, the path descends to the left towards the French lines, leading to the Courtine crossroads that you already know.
(6) Continue straight ahead (south) towards Barrenkopf. At the entrance to the Barrenkopf woods, you will see sign no. 19.
From the Barrenkopf sign, continue the circuit along the ridge trail towards Kleinkopf and its observatory. After about 30 metres, leave the Barrenkopf trail for a short while to enter the woods and discover a model trench (sign no. 20).
Return to the Barrenkopf trail. All along this ridge, there are numerous concrete remains, trenches and shell holes, which can be seen by stepping 5 or 10 metres off the trail. Shortly after passing the summit, you will come to the first French line at Barrenkopf in 1916. It is less than 20 m from the German trench.
(10) At Barrenkopf, leave the ridge path again on the left to discover the masonry façade of the arrival station of a small German cable car (sign no. 21). Then return to the ridge path. After a steep descent, the path climbs slightly to reach a rocky peak. An observation window is still clearly visible from the path. It is now at knee height, so hikers sometimes pass by without seeing it.
(11) After about 100 metres of rocky trail, you will arrive at a bare peak called Kleinkopf. Begin the descent to the left towards the television relay antenna. When you reach the Linge road, just below the antenna, you will find an orientation table (sign no. 23) located below the road.
(12) Next, take the path that descends to the left of the orientation table, which will lead you to a small pass called Wahlenstall. Take the forest path on the left, which will allow you to discover the relatively well-preserved remains of several shelters.
(13). From the shelters, retrace your steps.
(12) Leaving the crossroads, climb the small hill in front of you, following the edge of the woods, to find the remains of a German artillery observation post (sign no. 26).
You will now descend along the edge of the woods to reach the small pass (elevation 803).
(14). You will arrive at a crossroads of paths, where a wooden refuge hut has been built. Take the path climbing eastwards to reach another small pass called Schneiden on the southern slope.
(15) Here, a sign indicates the presence of an important structure.
Take the forest path on the left (west) to go around the Hoernleskopf on the left and return to the small pass
(14). Take thesecond road on the left and stay below the road to reach the car park (S/E).
