It starts south of Delle, 30 km from Belfort, near Saint-Dizier-l'Évêque, at the hairpin bend on the D57.
Markings: Blue Disc.
(S/E) Follow the track through the forest outside the hairpin bend. Find the path marked in both directions. The return comes from the east, the departure to the west. Take the path heading west for about 300m.
(1) Turn right to read the trail description sign located less than 100m away, just after the Champs Houdin farm.
(2) Retrace your steps to the previous crossroads.
(1) Take the wide stone path opposite leading to Croix. It will turn into a footpath.
(3) Take great care shortly before reaching the edge of the forest. There are two almost parallel paths, so look carefully for the blue disc markings and take the first right, which stays in the forest 50 metres from the edge.
(4) When you reach the D50, take the path opposite, which leaves the woods after about 600 metres.
(5) At the edge of the woods, you will see a marker for the Sentier des Bornes de la Principauté de Montbéliard trail.
Turn left and rejoin the D50. Keep right on the farm track towards Abbevilliers. Continue straight ahead under the high-voltage power line.
(6) When you reach the high-voltage power line for the second time, turn left. Leave a path on your right and continue until you reach a road.
(7) Cross the D482/D26 and take the path opposite leading to a farm.
(8) Just before the farm, turn left and enter the forest. Shortly afterwards, you will find the first boundary marker. Along the way, examine each boundary marker in detail. You will see the Bear of Bern on the Swiss side and the Fleur de Lys on the French side.
A little game: find a marker that is upside down, with the Fleur de Lys on the Swiss side.
(9) At boundary marker 329, turn right onto the Swiss path towards Fahy. A sign indicates that you are entering Switzerland. Continue for about 1 km before reaching the border at marker 328, at the edge of the forest.
Pay close attention to the markings on this section.
At the edge of the forest, behind the hedge, is a Swiss military training ground.
(10) At marker 325, the trail turns right. Shortly afterwards, turn left onto a small tarmac road that leads to the Paradis farm and then opposite to the Purgatoire farm.
This is where the refugees gathered and where the "Passeur" mission ended. The return journey was never made by the same route.
From the Purgatoire farm, take the D50 on the left and at marker 321, enter France. Take the path straight ahead that leads into the forest.
(11) After 300 metres, at the bottom of the descent, turn right and head north to join the
forest trail of Saint-Dizier-l'Évêque.
(12) At the fork, take the left path and then pass two tracks on the left. At the crossroads, turn left onto the farm track.
(13) When you reach the D26, turn right and follow it for about 100 metres.
(14) Be careful to ignore the yellow ring markings that go straight ahead, but turn left, then left again onto Rue Champs au Roi.
Continue straight ahead through the village. At the exit, head west into the woods, paying close attention to the markings.
At the first crossroads, go straight ahead, at the second, turn left and then leave a path on your right.
(15) Look for a marker with three stars engraved on it. Turn right.
(16) At the next crossroads, turn left and then 10 metres further on, turn right. Pay close attention to the markings in this section. Return to the starting point on the D57 (S/E).
