From the Houbirg summit, continue along the Ringwall.
Here you could (!) One section of the 4.5 km long ringwalls (for comparison, the Nuremberg city wall 4.0KM) from the Celtic period of about 1600 BC. traveled.
Please, let us spare this monument. It is also not very fun to drive highly concentrated over partly insurmountable rock and root pieces and to be constantly afraid of rollovers or slipping over the steep slope. Let's protect this monument instead of driving it. A path leads downstairs. As an example of the inaccessibility I pushed up the MTB times.
