From the car park of the Sixenhof local history museum, walk to the campsite Alpen Caravan Park Achensee. Turn right and follow the signposts to the Gaisalm mountain hut past the Seewinkel. Follow the narrow path (Mariensteig) as it climbs steadily alongside Lake Achensee before it descends over steep steps to the Gaisalm (shipping pier). The route leads over scree and narrow rocky trails to Pertisau and from here alongside the lake promenade to Seespitz (shipping pier). Continue along the lake promenade in the direction of Buchau and past the pier Buchau until you reach the Prälatenhaus. From here, the path follows the eastern lakeshore and leads past the campsite Achensee Camping Schwarzenau and the pier Achenseehof to the pier Scholastika in Achenkirch. Alternatively, you can complete the loop around the lake by ship. (Attention: The trail from Achenkirch via the Gaisalm to Pertisau has some narrow sections which require sure-footedness and a head for heights).
