Demanding mountainbike route over the two highest mountains in the Harz mountains - Brocken (1,142m) and Wurmberg (971m) The tour begins behind Torfhaus with a single trail in the beautiful landscape of the Hochharz and views to the Brocken. After a short descent, it goes over the Acker mountain to the water reservoir Sösetalsperre, where wonderful views to the regions of the Oberharz are possible. In the Oberharz itself, the route goes along several ponds of the UNESCO World heritage 'Oberharzer Wasserregal', on an old railway line and along the dark blue water reservoir Okertalsperre. The long climb to the Brocken begins after about half of the route. Wide views to the Harz foreland are possible before the 1,142-meter-high summit of northern Germany's highest mountain is reached. The ascent is rewarded with an approximately 15-kilometer descent before a final steep ascent to the highest mountain in Lower Saxony (Wurmberg) follows. The route leads downhill through the untouched nature of the Nationalpark Harz back to Torfhaus.
