The Bilstein embodies one of the most valuable natural rock complexes with relict character in Hesse with a unique flora and fauna.
High above the valley of the Wilde stream rise two impressive diabase cliffs, which bear witness to volcanic activity in the Lower Carboniferous period around 350 million years ago.
The Bilstein was first mentioned in 1841 because of its floristic rarities. After the Bilstein cliffs had already been designated as a geological and natural monument, the area was given its status as a NSG in 1999. Species can be found here that only occur once or a few times in Waldeck-Frankenberg, North Hesse or Hesse.
389 butterfly species alone have been recorded here, including over 100 that are on the red lists. 110 species of beetles and over 100 species of wild bees and wasps were found in the area.
On the upper of the two cliffs there is a viewing platform from which you have a wonderful view of the Wildetal and the Homberg. You can hike the Bilstein via three nature park circular trails as well as the Wildunger circular trails W1 and W2. The starting point is the Bilstein hiking car park in Reitzenhagen.
