From Fouday, take the D57 towards Waldersbach, then the D857 at the village exit towards Blancherupt. Park near the church.
Yellow ring markings
(S/E) Take the marked path up to the left after the church. This path climbs for 800 metres (this is the most difficult section of the route). At each intersection, keep to the path that climbs. Continue to the top of a bare ridge at La Boucherie (altitude 710 metres).
(1) Here, you can enjoy a beautiful panoramic view of the Champ du Feu massif and the village of Bellefosse, dominated by the Château de la Roche, which emerges from the fir trees. Walk 100 metres to the left and back to admire the view of the Donon massif and the Col de la Perheux.
Alternatively, turn right and follow the fence, continuing straight ahead at the first crossroads. You will come to a second crossroads.
Yellow ring and blue cross markings
(2) Turn right and follow the fence to reach a crossroads.
(3) Ignore the path climbing to the left and leading to the Château de la Roche (which you can visit). Continue through the forest. Leave a yellow signpost path on your right to reach a track. Continue straight ahead to the four-way junction.
Yellow ring markings
(4) Turn right and follow the markings. Descend to the left on the yellow-marked trail. Follow the same markings, which turn right onto a small trail, then continue straight ahead on the yellow-marked trail. You will arrive at a viewpoint overlooking Fouday with a bench.
(5) Continue on the Yellow Ring marked path to the left, then to the right. After the stream, continue straight ahead. At a large hairpin bend to the left, continue straight ahead on the Blue Triangle marked path which leads you to the village of Blancherupt. Continue to the next crossroads.
(6) While the Blue Triangle marked trail descends into the village to the left, continue straight ahead (path leading to the Yellow Ring markings). You will cross the pastures of Blancherupt. Further on, at the crossroads, descend to the left on the Yellow Ring marked trail (note a new calvary on your left) to reach the village and the starting point. (S/E)

As mentioned, the beginning was the hardest part: a steep climb, at the end of which you are rewarded with the kind of scenery I love to discover. The paths are pleasant and well chosen for this half-day walk. Thank you to those who made it available! PS: the smallest village is also worth visiting, and there are some good restaurants in the surrounding area (a few kilometres away).
