The Brasselsberg mountain close to Kassel, Germany, is full of rock formations of volcanic origin. There were different volcanoes and over time erosion washed weaker material out and left bizarre rocks throughout the mountains. Some are better known as they are located next to frequently used hiking paths (like the Porta Lapidaria) and some are very special like the Teufelsmauer and facilities like protective huts have been created next to them. A rather unknown beauty are the Bilsteinklippen, a collection of large volcanic rocks near the Bismarckturm.
When you’re up there and at the roundabout next to the Bismarckturm you should take the short detour to visit them. They are mostly covered with moss and platts that don’t need direct access to the ground. These plants gather the necessary water from the air and from rain. Unfortunately, you can only observe them from a road leading along – it would be great to have a small path to climb up in between of them.
