Lac de Sewen walks

A peaceful hike that will take you to Sewen Lake and its peat bogs, then to Alfeld Lake, which is very different with its dam. The path is flat until you reach the foot of the dam, then climbs a little.

Along the banks of the Doller and then the Wagenstall waterfalls, reach the peaceful stubble fields of the narrow Grand Langenberg valley near an authentic farmhouse inn. Then 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 along the left bank of the Doller (marked with triangles and red trestles) and rejoin the route at point (1) or point (3).

This is a beautiful hike offering views of and above the lakes. You will feel cool as most of the hike takes place in the forest (open areas: downstream from the Baerenbach farmhouse inn, the same for the Gresson moyen and the Haute Bers).

Discover the Roches de Morteville, Lake Sewen and Lake Alfeld, the large rock, the statue of Joan of Arc and the waterfalls. A hike bordering on the (very) difficult. GPX track strongly recommended. Route between (5) and (7) updated on 13 May 2025

A hike that requires sure-footedness. The path is sometimes slippery from the start up to the Col de Rode Tête, setting off from La Jumenterie to reach Ronde Tête via Lake Alfeld and its waterfalls. The route passes through Sewen and its lake before heading up to Wisgrutt. From there, theGR®5takes us back to the foot of the Ballon d’Alsace to climb to its summit: the Vierge, an orientation table and stunning views of the surrounding area. Finally, we pass by the statue of Joan of Arc before returning to our starting point.
