Access to starting point:
From the border crossing Šentilj we continue driving on the highway towards Graz and further towards Linz and Salzburg. We soon leave highway A9 and continue driving slightly right in the direction towards Vienna / Wien and continue driving on the expressway S35. We leave the mentioned expressway at the exit for Mixnitz, and then from the roundabout we take the exit in the direction of Teichalm. We continue to follow the signs for Teichalm. At the end of the settlement St. Erhard, a road branches off to the right towards Teichalm, and we continue straight, following the signs for Straßegg, Hartberg, Birkfeld, and Gasen. The road then starts to ascend more noticeably, and we drive to the mountain pass Straßegg, where the guesthouse Stroßeggwirt is also located. The designated parking lot by the guesthouse is intended for guesthouse guests, so we park in an appropriate place nearby.
Path description:
From the mountain pass, we follow the path towards Sommeralm and Teichalm, initially walking on a macadam road that soon leads us to a spot with several crosses. We bypass the crosses on the left, continuing on a cart track, which we leave after crossing a grazing fence, proceeding slightly left on a steeper footpath. After a few minutes higher up, we exit the forest, with beautiful views opening up to the right and behind. Next follows a forested ascent and higher up a crossing of a poor forest road, which we later return to. We continue on the road, which soon begins descending; before the fence, we veer slightly left onto a footpath. Next comes a short passage through the forest, and after a cross, we leave the forest, followed by a brief, steeper descent on a grassy slope. The path then leads to a cart track, which, near the Pöllabauerkreuz cross, joins a macadam road.
After a few minutes, when the road enters the forest, we take a marked cart track that ascends steeply, continuing straight at several crossings.
When we reach the southeastern slopes of the mountain Zechnerschlag (Rohregg), we exit the forest and, with a gentle descent, arrive at a nearby road and, a few dozen steps further, the cottage on the mountain pasture Haberlstall Alm.
From the mountain pasture, we head south, and after a short ascent, the path splits. We bear slightly left, following signs for Sommeralm (slightly right for Heulantsch), then diagonally ascend on a cart track. Upon reaching a panoramic grassy ridge higher up, we continue straight (right for Heulantsch), then moderately descend to the next crossing, where we turn left (right for Teichalm).
We proceed in the direction of Sommeralm signs, and the path on the other side of an indistinct saddle splits once more.
We continue slightly right (slightly left to Stoakogelhütte cottage), then follows a diagonal ascent through a strip of forest. When the forest ends at a few crossings, we continue straight, or follow the signs for Sommeralm; a wind power plant can also aid in orientation.
From the crossing at the wind power plant, we continue right (left to Plankogel and Stoakogelhütte cottage), then gradually descend to an asphalt road, which we follow right to the center of the Sommeralm settlement.
Straßegg - Haberlstall Alm 1:25, Haberlstall Alm - Sommeralm 0:50.
