Halde Minister Achenbach IV - Tockhausen
If you give priority to a good view of the surrounding area, then you are wrong here. You get that in some places, where the vegetation becomes more open or was cut free and gives you some great views. With good visibility you can see not only the old mines Minister Achenbach shaft 4 with the Lüntec Tower ("Colani egg"), but also the Lünen power plant and the city center, but to the Dortmund city center.
But if you are looking for a not only suitable for hiking, but also suitable for cyclists, then you will enjoy the diverse vegetation. Many animal and insect species have found their home here in the forest-like dense vegetation. The heap is developed by a very interesting network of paths, which allows you either a very fast and steep, or just a flatter and longer climb. With the bike offers the shallower ascent and the steeper descent, as soon as you have the basics of driving and braking technology half way out. Of course, it makes much more fun on the MTB even for less experienced ;-)
