Lake Sewen

This lake in the Alsatian Vosges is one of the rare intact glacial overdeepening lakes according to geologists. Now reduced to 6 hectares, it covered more than 30 hectares at the end of the 14th century, since invaded by peat which gives it its unique character. Protected for its wildlife and flora, it is home to beavers and carnivorous plants such as sundews, attracting the attention of botanists and zoologists. In warm, humid weather, will-o'-the-wisps can sometimes be seen on its peat edges, adding a mysterious touch to this preserved natural site. Around the lake, activities are limited: fishing and walking are allowed, but swimming is strictly prohibited. To access it, just a 15-minute walk from the village, where parking is available at the Church square. The Sewen lake circuit allows visitors to discover this site in complete tranquility.
