Access to starting point:
Highway A2 Graz - Vienna / Wien we leave at the exit for Gleisdorf West, and then we follow the signs for Hartberg and Weiz, and later only Weiz. At the beginning of the town Weiz, we exit the roundabout towards the exit for the settlement Birkfeld and then follow the road all the way to the mentioned settlement, from where we follow the signs for Ratten and Rettenegg. At the beginning of the settlement Rettenegg, we turn left into the center of the settlement, where we then park in one of the marked parking spaces in the center of the settlement.
Path description:
From the parking lot, we continue on the sidewalk by the road which leads through the main part of the settlement. Before the road sign marking the end of the settlement Rettenegg, we turn left following the signs for Alois-Günther-Haus am Stuhleckgipfel. The path ahead leads us on the road Stickl Bergweg, along the same route as the marked path, which also coincides with the Planetary Path "Nebesa na Zemlji" / Der Planetenweg "Himmel auf Erden". Along the way, we notice planetary points of this path, equipped with information boards. Next follows an ascent above the settlement, where a beautiful view of Rettenegg opens up when looking back. Then, we ascend through a strip of forest. When the forest ends, we reach the settlement Sticklberg, where we continue straight from the crossroad, passing by nearby buildings of a homestead.
Behind the homestead, the road turns into a macadam path. Further on, at several crossroads, we follow the blazes or signs for "Planetenweg". When we re-enter the forest, we turn left from the road onto a cart track and immediately right onto a footpath that ascends along the edge of the forest. Just a few minutes later, we cross a macadam road. The path then continues partly on cart tracks and, in shorter sections, on the macadam road. The path, which has a few more crossroads and individual information boards of the Planetary Path, higher up turns into a steeper mountain path. This gradually leads us out of the forest onto grassy slopes, across which we first ascend diagonally to the right, then continue along a grazing fence fairly straight uphill. The path flattens at the marked crossroad on the saddle Schwarzriegel, where we turn left (right Stuhleck) towards Mürzzuschlag and Roseggerhaus. We gradually enter a strip of sparse spruce forest, where the terrain levels out. The path continues through a short swampy section, where it runs over wooden boardwalks.
We quickly leave this section and reach a wind power plant park, before which there is a warning sign indicating the life-threatening danger of falling ice from the power plants.
Soon after the first power plant, we cross a macadam road; before the next power plant, we go left and return to the road, which we cross a little lower down. We follow the road to the right, and in a few minutes, we reach an indistinct peak, Grazer Stuhleck.
Next follows an easy descent on the macadam road, and we continue with nice views among the wind power plants. When the descent ends, we start ascending again, and in a few minutes of a moderate ascent, we reach a grazing fence that also crosses the road. Here, near the grazing fence, is the highest point of the peak Geiereck.
Next follows an easy descent to a marked crossing, from which we continue left in the direction of the mountain hut Roseggerhaus (right leads to Moschkogel and Moschkogelhütte). Further on, we walk on a gently sloping road, and in a few minutes, it brings us below the peak Pretul, where, on the left side, only a few steps from the road, we notice the guard tower Peter-Bergner-Warte on the mentioned summit.
We bypass the tower on the right side, then turn left from the road onto a footpath toward the mountain hut Roseggerhaus (continuing on the road Amundsenhöhe). Next follows approximately a ten-minute descent, and we arrive at the mountain hut Roseggerhaus.
