Departure from Sewen (Haut-Rhin)
Follow the banks of the Doller and then the Wagenstall waterfalls to reach the peaceful thatched cottages of the narrow Grand Langenberg valley near an authentic farmhouse inn. Descend to the foot of the Ballon d'Alsace towards the impressive glacial basin of Lake Alfeld, which dominates the Doller Valley. Finally, return along the tumultuous Seebach, which calms down in a wet and marshy meadow before dying in the peat bogs of Lake Sewen.
Please note that theGR®531is sometimes obstructed (forestry work, overgrown vegetation, fallen trees, etc.) and maintenance is sometimes delayed. In this case, take the Fennematt path that runs along the left bank of the Doller and rejoin the route at point (1) or point (3).
