Achterbahn

From Blaustein along the Danube cycle path to behind Arnegg. Before the gravel path, go up left, then right again. In left/right combinations, always go up. At the top, go west under the high-voltage power line. Steep and winding down, then steep and winding up to just before Erstetten. Then over Allewind through the woods towards Roter Berg. Before that, turn left down the gravel path towards Aldi Blaustein.
