In the area of the Born anticlinal fold, the groundwater horizon in the red sandstone has a higher level than the Sûre river, so that springs emerge. When the Sûre is low in water a source becomes visible whose water has a high salt and iron concentration. This water was used from the 16th (1587) to the middle of the 18th century (1749) for salt extraction by grading. Grading means that the salinity of the water from such a source is increased because the water evaporates naturally by wind and sun. Thus, heating energy is saved for the subsequent boiling of the brine. In the middle of the 18th century, the saline plant was shut down. Reasons for this could have been the emerging lower degree of saturation of the source on the one hand or political reasons on the other. According to legend, even today the little salt man appears at the spring around midnight and frightens passing hikers. Those who misappropriate foreign property are particularly tormented by the salt man. The Salzwaasserquell can be hiked via the Auto-pédestre Born.

The starting point of the hiking trail is located behind the school and sports complex near the village of Born an der Sauer. At the starting point of the path is the "Salzmännchegaart" with a geological barefoot path. After an ascent to the Wangertsbierg, you will be rewarded with beautiful views of Born and the Sauer valley. After a landscape lined with fruit Bongerten and dry stone walls, the path leads into a forest area. Here it passes rocks and then dry grassland above Moersdorf. There is also an orchid educational trail. On the Burer Bierg plateau there is a seating area where you can enjoy the beautiful views of the surrounding area. Afterwards, it goes back down to Born.

The hiking trail starts at the school and sports complex near the village of Born. At the beginning of the path is a geological barefoot trail "Salzmännchegaart". The ascent to Wangertbierg is rewarded with wide views over the village of Born and the Sauer valley. Then the path leads along regionally typical orchards and dry stone walls into a forest area. The path passes rocks and dry grassland above the village of Moersdorf. Here the path runs together with the orchid nature trail of the Fondatioun "Hellef Fir D ́-Natur". Then it goes back down to Born.
