Kohlbauernaufsatz, entered from a small stream near Unterach, splits into two moods either side of the entry: open meadows on the shallow left that suit less experienced divers, and a wall on the right dropping from 18 to 32 m. On flat ground at the base of the wall a small wooden rowing boat with a tiny outhouse perched on it has earned the nickname the Attersee's 'Titanic'.
Where it is and how deep
47.8201° N, 13.5093° EApproximate position — the dashed circle shows where the site lies; your operator's briefing has the mooring.
The dive
From the entry at the stream, the dive splits into two directions. To the left the bottom stays shallow and opens into extensive underwater meadows, an easy, low-pressure profile that suits divers still building depth and buoyancy skills. To the right the ground gives way to a wall that drops from around 18 m to 32 m, a straightforward, well-defined face rather than a maze of ledges.
At the base of the wall, away from the rock on flat ground at 32 m, lies a small wooden rowing boat with a miniature outhouse fixed to it — a private joke among local divers, who call it the Attersee's answer to the Titanic. It is a modest, slightly absurd payoff for the depth, and a popular photo subject for anyone who makes it that far down.
Fish life is more visible here than at the deeper technical sites on the lake: pike, perch and roach work the meadow and wall edge through the day, and eels come out into the open on night dives. The contrast between the gentle meadow and the sheer drop close beside it is the character of the site, and it rewards a dive plan that picks one side or the other rather than trying to cover both.

Season follows Attersee: Diving runs year-round; visibility peaks near 30 m in winter, while July and August bring more bathers, boat traffic and sometimes murkier water.
Know before you go
- The wall edge drops abruptly from the shallow meadow side; drifting right without noticing the transition can put a diver on a 18 to 32 m face faster than expected.
