Challenging full-day hike with 1,280 metres of elevation gain and stunning summit views. Refreshments available at the start and end of the 7.5-hour route.
From the car park Sonnberg at the biomass cogeneration plant, walk to the Zöhreralm mountain hut (1,334 metres). Follow a steep forest trail, then walk between mountain pines and over the ridge to the Hochunnutz (2,075 metres) via the Hinterunnutz. The trail descends to the left and leads around the moderately difficult ridge of the Vorderunnutz before it climbs to the summit of the Vorderunnutz (2,078 metres). Walking across the ridge and descending between mountain pines and over craggy slopes to the Köglalm mountain hut (1,431 metres) is recommended for experienced hikers only. Walk past the Köglalm and follow the trail to Achenkirch which joins the forest road to the valley. Follow the signposts “Panoramaweg” in a northerly direction to the biomass cogeneration plant.
Take the regional bus to Achenkirch (line 4080 or 390) and get off at the Achenkirch Bäckerei stop. From there, walk a short distance along the Dorfstraße towards the lake, then turn left uphill at the next road. Continue through the underpass beneath the Achensee main road (B181) to the car park next to the biomass cogeneration plant.
