Am Hornpottweg is a small nature preserve that used to be a gravel pit. Today, it is a marsh surrounded by a forest loop trail. To make sure this preserve stays a marsh, there are grazing Galloway cattle, as well as two water buffalo. Of course, you can also observe wildlife, including 69 bird species such as Eurasian nuthatch, woodpeckers, and egrets. Am Hornpottweg is also considered a resting area for migratory birds. If you are lucky, you might also spot some common toads or Eurasian tree frogs.
Although the loop trail around the gravel pit only takes about half an hour, you can extend your hike in the surrounding wooded areas. You could even walk to the Strand Von-Diergardt-See (literally the Lake Von Diergardt Beach) to swim (26 min by foot). Also in the vicinity of Am Hornpottweg, you will find the restaurant Waldschenke where you can eat German food with a Mediterranean twist, and which has a lovely Biergarten surrounded by trees (beware of the wasps in Summer)!
From Appellhofplatz in the city center, you can reach Am Hornpottweg in 42 min and directly with the U-Bahn line 4.
