The tour starts at parking lot 3 - Seyfried, just 2 km behind the former Braun inn in Triebental.
We follow the large meadow in a SW direction to the edge of the forest, where we meet the forest road. Now we follow the forest road (marked S5) to the Steiner Alm (Triebener Hütte, 1,646m).
Behind the hut, the route leads us across the slopes in a south-westerly direction towards Triebener Törl. Triebener Törl is the saddle between Griesstein and Sonntagskogel. Once at the Törl, we first follow the ridge/ridge to the Sonntagskogel. We make a good track in the flank that leads to the summit of the Sonntagskogel. The last, very steep section to the summit can be tackled without skis.
The descent follows the ascent track.
