    Hiking

    "Altenrath Clay Pit in the Wahner Heide - A great deal of clay was extracted in the area of today's Wahner Heide. Evidence of this can be found in the traces left by the Altenrath potters of the
    17th century, the "Ludwigshütte" clay factory, and finally, the Altenrath clay pit on the edge of the airport grounds.


    From 1968 to 1982, clay was extracted here on a large scale (partly illegally). After extraction was halted due to numerous protests, the pit served for some time as a dumping ground, and the pond was used for swimming."
