Situated in the valley of the Moselle, this important nature reserve attracts many wetland birds. It consists of ponds and marshes in an area where there was once gravel pits. There is a waymarked path with several observation posts allowing visitors to watch birds and other wildlife. There is plenty of interest at all times of year and in spring 80 species of bird may be spotted. Autumn is a good time for seeing birds on migration. The reserve is signposted on the outskirts of Wintrange on the Remerschen road.
