Like other lakes, below the Tête des Perche. On the other hand, the signage, at the Col des Perche: could do better!! For the Tête des Perche or the Lac D'Alfeld... So, for the Lac D'Alfeld: follow Ballon d'Alsace until an intersection on the left. I lost an hour: returned at night!

It is possible to walk around the lake, but in the part opposite the dam you have to walk through large boulders without a path. But it is doable. The path is usually 1-10 meters above the lake surface.
