From the car park of the Achenseeschifffahrt, follow the short dirt path along the lake until it joins the rocky trail to the Gaisalm. Walk over scree and narrow sections until you arrive at the Gaisalm mountain hut. From here, a steep trail climbs through rocky terrain to Achenkirch. The northern lakeshore is not accessible, but a little detour takes you to the pier Scholastika. The return is via the same route or 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).
