Starting from Tirolgraben (P), we briefly follow the forest road and then cross a meadow, heading diagonally left uphill. Continuing on the marked forest road, we can shorten the switchbacks by following a well-recognizable but unmarked trail.
Where the forest road crosses the Lachalmgraben (concrete bridge), we turn left onto another unmarked trail that climbs fairly steeply to Lachalm. From here, we follow the marked path to the Hinteralm, taking the so-called "Ausgang" (exit) route and finally ascending to the Alm via Kapellerbergl. From here, we follow the marked path to the Spielkogel summit.
For the return, we follow the same route back.
