Located in Kassel, the Bilstein Hills are just over 460 meters above sea level. These hills are characterized by the presence of flowing water in it, which falls from its height to the agricultural lands below, so the area there is evergreen and very rich in plant wealth, trees and rare wild shrubs. These hills overlook the entire city, where from their summit you can watch golden sunsets and the reflection of sunlight on the ponds and waters of Castle.
