Source de la Doller 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 this trail of bunkers, explore fortifications dating back to the First World War, built by the German army. After the fighting in the summer and autumn of 1914, the Haute-Alsace front stabilised on along the line of Cernay-Dannemarie. The commune of Burnhaupt-le-Bas remains on the German side. In December 1914 and January 1915, the French offensive in this sector regularly broke the German lines at the cost of many lives.

This hike will take you to the Source de la Doller, which, contrary to what you might think, does not originate at the Ballon d'Alsace, but below the Schlumpf. During the hike, you will enjoy beautiful views of the Doller valley and have the opportunity to eat at one of the farmhouse inns along the route.

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).

This beautiful hike takes you from Masevaux to the summit of Rossberg at an altitude of 1,191 metres. From the top, you can enjoy magnificent views of the Vosges, the Alsace plain, the Black Forest, the Jura and the Alps. The elevation gain is significant, but the route is otherwise easy.

This hike takes you mainly through forest from Sentheim to Masevaux via the Wolflenloch discovery trail. The return route follows the Doller river, passing the Hohenstein Cave and Sainte-Anne Chapel.
