Easy mountain bike tour starting in Bad Harzburg and beautiful views of the dark green mountain slopes of the Brocken The tour begins with a longer ascent up to the Kästeklippen area. From there the route leads to the Huneberg quarry. In the active quarry, mainly diabase rock is extracted, which is mainly used for road construction. From the quarry there are several viewpoints with a view up to the massive mountain slopes of the Brocken. The route then crosses the 'Bundesstraße 4' between Bad Harzburg and Torfhaus and then reaches its highest point above the Ecker dam. Now it goes through a varied landscape with several unique views of the Harz foreland downhill through a valley back to Bad Harzburg.
