We discovered a beautiful and new-to-us walking route near Stolberg this week.
It crosses through a military practice and war memorial site (hence the abandoned tanks!), meaning part of the walk is not always accessible.
It is a gorgeous tour, about 7kms in length, featuring grassland, water, forget-me-nots, oaks in fields, grass and heather, mixed woods, and even a small grove of enormous spruces.
A GPS map of this walk can be found at ich-geh-wandern.de
