I needed 4 hours! From the Ammerwaldbahn back about 800m, then turn left at the small parking lot. Keep right at the junction. Shortly after the sharp left-hand bend, the right-hand side of the climb (I did not see it immediately) begins to show sparingly red dots. Continue straight on the summit, always on the ridge or on the ridge to the north summit. Then turn left (careful), on the other side of the ridge in the Weitalpjoch. There follow the sign "Roggental" or "Ammerwaldalm" to the parking lot The descent is mostly rocky The tour is predominantly sunny.
