24 Haldentour vier Halden im Revier

4 spoil heaps, 4 times good views over the region, 2 former state garden show parks. Start at the Centro, those who want can visit the 115m Gasometer (lift), through Olga Park to the Jakobi golf course, to the Haniel spoil heap, down via the Kreuzweg to Bottrop to the Tetraeder (The new bridge between the Tetraeder and Alpincenter is not yet on Google). The climb is worth it here. Then proceed to the Nordstern Park and on to the Schurenbach spoil heap. Along the canal or the Emscher, head now to Haus Ripshorst and then to the Knappen spoil heap. It's not far back to the Centro from there.
