Leave the Posthotel Achenkirch via the left exit. After the bakery, you will reach a yellow building (Österreichische Bundesforste AG) on the left side of Dorfstraße street. After this building, a narrow road leads left through an underpass. This way will take you to the car park of the former Sonnberg lift. Here, you find a signpost to the panorama trail (Panoramaweg). After a short ascent, you can follow the path straight to Lake Achensee.
From there, cross the main road and walk through the village to the Christlum lifts (Hochalmlifte Christlum). From here, walk to the entrance of the Unterautal valley and then head north for around 100 metres until you reach the start of the Karwendelweg path. This path takes you across a high plateau to the golf course that crosses over the Blasenbach stream and finally leads to the Falkenmoos forest path.
Follow this path down towards the village. Pass the Kalvarienkirche church, and you will reach the bus stop “Achenkirch Abzweigung Steinberg”. From there, take the underpass and walk left along the asphalt road towards “Alter Steinbergweg” and then back towards the Posthotel Achenkirch.
