A hike along the Donon fortified positions trail. From September 1914, the Vosges front stabilised on the ridges and the Donon became a defensive position of prime importance. In 1915, the Germans embarked on a colossal construction project.

Description of the walk

Parking at the start of the Route Forestière de Prayé near the Col du Donon towards Raon-sur-Plaine.

Red ring markings

(S/E) Take the Sentier des Fortins.

(1) Turn right and you will soon see the first blockhouse, which you cross for a few metres. At the exit, continue to the right and after about 600 m, you will reach a second blockhouse, which is a little longer to cross.

Continue along the path, pass the Haute Abraye shelter and take the path opposite that runs alongside the road and leads to a crossroads. Cross the crossroads to reach a battery of guns on gun carriages and continue to the Étoile 1 crossroads.

(2) Continue straight ahead and immediately turn right onto the forest road.

(3) Keep right and at the next intersection, take the road uphill to the left. At the clearing, the trail continues uphill to the left and winds between small blockhouses to emerge at a machine gun emplacement crossed by a narrow 60-metre tunnel. Further on, take a sharp left turn and pass two casemates on the hillside.

(4) Continue to the right for about 800 m.

(5) Turn left at an acute angle.

(6) Leave the track to the left through the heath and follow two large howitzer batteries to reach the Étoile 2 crossroads.

(7) Take the path opposite and slightly to the left that descends into the forest.

(8) Go up the road to the left.

(9) Turn right twice to follow the battery of cannons seen at the start of the route. The gun ports are clearly visible. Continue for a few metres.

(10) Head right and follow a path through the woods that leads to a track. Follow this track to the left, where you will find an artillery battery and a huge casemate reserved for the headquarters.

(11) At the crossroads, turn right to reach the Donon National Necropolis.

(12) Enjoy the spectacular view of the Donon. Walk about 200 metres.

(13) Turn left onto the Sentier Jean Maegey.

(1) As soon as you enter the forest, turn right to reach the car park on the Route Forestière de Prayé (S/E).

The hike is very pleasant with a variety of paths: forests (many) and meadows (a few). The view from Mathieu Diem is remarkable (not mentioned in the description!!). Visiting the bunkers is unlikely, as they are all brand new (never used). There are dozens of them, well preserved and scattered throughout the route. The arrival at the necropolis and the view of the Donon alone make the walk worthwhile.

A superb short, shaded hike with no significant difficulty between trenches and blockhouses.
Very pretty landscape at the highest point of the Corbeille massif (899 m) among shrubs, heather and brambles.
There is a 360° view of the Lorraine plain, the Petit and Grand Donon, the Hautes Vosges and the Alsace plain.
The more daring can climb up to the viewpoint at Point de vue Thierry DIEM (be careful, the steps are starting to get old, so it's best to climb one at a time...)
Numerous blockhouses and other shelters are scattered along the route. Almost all of them can be visited (without danger) and most are well preserved.
It's just a shame that there isn't more information on site (signs) about these military structures to explain their functions and uses.

Please note that part of the trail, including the most interesting forts, is closed to hikers for several months due to animal breeding. This is a shame as the trail is very interesting

A pleasant, shaded hike at altitude on this hot summer's day
We didn't go inside the forts as we didn't see the point. It is possible to walk around them

A beautiful hike to do in warm weather to discover the remains of the army (World War I), very interesting. Few people on the trail, which is very well marked throughout. Easy hike.

A very beautiful hike, but please note that part of the trail is closed from February to July because it is located in a protected breeding site (Natura 2000) for a protected species. However, you can easily avoid this by taking the left path at point 3 to go directly to point 4, and once there, resume the normal route.
For almost the entire walk, you can follow the red circle markings, except at point 3 (as it is closed after that), but the signs are easy to find.
The walk has the advantage of taking you right through the fortified structures, which is great fun. However, you should take great care with dogs and children as there are areas with holes and accidents can happen quickly. Ladies and gentlemen who are over 1.70 metres tall, I would strongly advise you to keep your heads down in the structures ;-)
The views from the first peaks are also very beautiful and the charm of this forest is very much in evidence.

Hello, a beautiful, original hike off the beaten track. The Corbeille massif between points 3 and 4 was closed, so we went around it via the lower path (a wildlife sanctuary). For more information on opening dates, call the Schirmeck tourist office. A torch is recommended.

Hello, hike completed today. It was hot, but there was shade almost the entire way and it was cool inside the blockhouses. However, at the second bunker, the red ring markings were missing, and I ended up on an unmarked trail. Luckily, I had my Garmin GPS to find the shelter afterwards. Otherwise, it was a superb, historic hike. Bring a torch. 14 km in total. 👍

A pleasant ride with no one else in sight along the entire route , and no one in the blockhouses along the way either.
However, the entire tour took 2 hours and 50 minutes instead of the 4 hours advertised, which was strange since we had the exact route...
A torch was very useful along the long corridors.

Hello, hike completed today. It was certainly hot, but there was shade almost all the way and it was cool inside the blockhouses. However, at the second bunker, the red ring markings were missing, and I ended up at a path with no markings. Luckily, I had my Garmin GPS to find the shelter afterwards. Otherwise, it was a superb, historic walk. Bring a torch. 14 km in total

A beautiful hike with lots of bunkers to visit, don't forget your torch.
Several passages through tall grass and ferns, watch out for ticks! Insect repellent is essential.
