TG18 Osterhorn-round

The tour begins directly at the inn Voglauerhof. After crossing the main road and the bridge over the Lammer, turn left. After 600 m uphill to the right, you pass an abandoned gravel pit. To the left past an old forester's lodge, later over a bridge, after 2.5 km there is a turn-off to the right towards Seewaldsee lake, Kühbichl, Brunnberg-farmer. Past the farms, you reach a short descent at kilometre 5.1. Afterwards, the trail continues up a gentle slope into the so-called Marchgraben (ditch). At kilometre 8.6, after a ridge, you reach the Seewaldsee (lake) nature reserve. Be sure to take a break here on one of the numerous benches or quench your hunger and thirst in the Auerhütte (hut) at the western end of the lake.

Continue, now on asphalt again, in a descent to the Seewald farmers. At kilometre 11.4, turn right towards Sommerau. Leave the turnoff towards Trattberg on the right and descend the road to the Vitalhotel Sommerau. At the junction below the hotel, turn right towards Bergalm and follow the road through the Strubklamm gorge. Later it gets a little steeper again, past the Grundbichl inn, you now continue on gravel to the Bergalm. Here we recommend a rest in the Bergalmhütte or the Neureithütte. The view of the Salzach valley and the Hoher Göll is fantastic.

Behind the Bergalm, turn left at a wayside shrine and follow the trail, later a forest path in several hairpin bends to Hintersee (kilometre 34.4). At the church in Hintersee, turn right and follow the road slightly uphill to Lämmerbach. From here, a steeper climb begins, but the last of the tour, to the Genneralm. At kilometre 41.8 you reach the highest point of the mountain bike tour (1325 m), the Genneralm, between Gennerhorn and Holzeck. The trail continues on an alpine path, later on a forest path and a forest road into the Ackersbachtal valley. Along the stream you ride through a narrow valley until you reach the old Postalm road. At this junction ( km 49.6), turn right downhill until you reach the approach road at an old forester's lodge. From here back to the starting point of the tour.
