The great relief wall is quite far away from all the other buildings, but is still quite easy to find. You walk along the straight main path through the beautiful forest (first beech, then oak, in one place spruce) to the end. Where this path, on which trucks often drive (to transport rubble), continues at a right angle to the right, you take the clearly visible path that leads further into the area in a slight left curve. The prohibition signs, usually high up in the trees, indicate almost reliably where it is or could be interesting.
Caution is generally advisable, not only because of the wild terrain and many tripping hazards, but also because of possible ammunition remains. But the latter problem applies to absolutely all former military areas on former GDR territory, which are often huge and sometimes represent wonderful excursion destinations as sandy heathlands. Warnings are everywhere and constantly. But in 34 years, no one has ever heard of any accidents, and no deer have ever been torn to pieces. So the whole thing with the prohibition signs seems to me more like a government obligation and economic protection, purely from an insurance point of view, and less like a serious threat to pedestrians and cyclists.
