Erlaufsee – Tauchzone
The only true mountain lake in this region, on the Styria–Lower Austria border near Mariazell. Diving is limited to the south-western (Styrian) shore, from about road km 3.1 of the Erlaufsee road to the Steinbach inflow, and you may only enter at the two signed entry points. Flooded trees, a steep wall and plenty of fish – lake trout, grayling, pike, perch, rudd and char – are the attractions; visibility can reach 30 m in spring and autumn, but the bottom is silty and plant growth is sparse. Divers also report training platforms to the right of the main jetty.
Tiefe: 0–38 m
