In 1910, the end of the Lüschersee was sealed on the Heinzenberg. The lake basin was drained. The end of the Lüschersee is, however, only part of the exciting story of the landslides on the Heinzenberg. Large-scale forest clearance and a destructive torrent caused landslides. Only a large-scale project with complex countermeasures and sometimes massive interventions in nature and the landscape provided a remedy. The adventure trail on the Heinzenberg tells all this and much more. At over a dozen information points, young and old are given a lot of exciting background information. The free hiking guide with lots of additional information is available free of charge at the Glaspass and Obergmeind access portals. There is a well-equipped barbecue area at the Lüschersee, and firewood is available.
