Lac d'Altenweiher, reservoir in France
Lac d'Altenweiher is a small reservoir in the Mittlach valley near Metzeral, surrounded by forests and mountain peaks. Clear water and walking paths circle the lake, offering views of the surrounding landscape.
The lake was created as a reservoir to supply water to local farms and homes. Over time it shifted from being purely functional infrastructure to becoming a place for recreation and relaxation.
The lake's name reflects the region's Germanic heritage and cultural connections. Visitors can observe how locals use this space for everyday leisure, gathering for walks and simple outdoor meals.
The lake is easily reached by car or bike from Metzeral with parking available near the entrance. Walking paths are gentle and safe for families, with rest benches positioned along the route.
The lake surface freezes over in colder months, creating a smooth white contrast against the dark peaks surrounding it. In spring and summer, wildflowers bloom along the edges and attract butterflies and birds.
