The Mattheiser Weiher consist of the lower mill pond and the upper Herrenweiher and form on 1.5 hectares the "Volkspark Trier-Süd", a recreational and nature reserve.
The artificially created lake in the 1970s is one of Echternach's main attractions. The approximately 4km circular path around the lake is highly recommended.
In the middle of Trier district Weismark lie the Pfahlweiher. A very popular recreational area for young and old. The ponds consist of two large, very idyllic and quiet in the forest fishponds.
