This hike through an unspoiled landscape begins at the Baraque Michel, built in the XIXth century in the middle of the moorland. During fog or snowstorms, a bell was rung to guide the lost out of the peat bog...Under the wooden paths that we follow from the hostel, water gurgles and flows from everywhere. We are walking on a huge sponge. The recent clear-cutting of the spruce forests is intended to restore the environment. Because if conifers cover the plateau today, the area once resembled a huge moor. The hike leads through the High Fens to the Cross of the Betrothed, a poignant testimony to the fate of François and Marie, who froze to death in January 1871 after getting lost in a blizzard... The endless expanses of the fens now give way to the beautiful landscape along the Polleur stream, which has remained so unspoiled that the path has to make its way through the alders and birches. It leads us to a place called "The Six Beeches", an island of deciduous trees in the middle of a coniferous forest. The way back leads through the Setay Fens.
