The pond „Landschaftsweiher“ in the valley called „Bottental“ near Erfweiler has a long history dating back to the 18th century. Originally, it was created under the name "Neuwoog" for fish farming. Such ponds were typical for the region at that time and served as an important source of fish, a staple food. Over time, the pond lost its original function and became overgrown. In 1983, the municipality of Erfweiler decided to redesign the pond as part of a recreational area. It was integrated into the "Langental" local recreation area and enhanced in terms of landscaping.
Today, the „Landschaftsweiher“ is a popular excursion destination. It is located along a well-maintained circular trail to the Eibach spring, offering benches for relaxation and providing picturesque photo opportunities throughout the year. The natural surroundings make it a peaceful retreat for visitors and a habitat for wildlife and plants.
