Halbinsel Au is a steep Lake Zurich wall dive with a park approach, but the Vorder Au entry is closed for repairs until April 2027.
About Halbinsel Au
Halbinsel Au is a classic Zürichsee wall dive with a shore entry through the park, a steep drop-off, and a long profile full of cracks, crevices, boulders, and small pockets of structure. It suits experienced cold-water divers who want a demanding freshwater wall rather than an easy training site, with burbot, perch, pike, bass, and trout among the most likely sightings when the site is open.

Depth range, seasonality, and planning context.

Best Season
Year-round when open
Typical Conditions
Cold freshwater, a steep wall profile, cracks and crevices, boulders, and limited shelter; boat traffic matters near the landing stage.
Safety & Access At Halbinsel Au
Hazards, restrictions, and access requirements.
Key Hazards
Boat trafficOverhead environment
Safety Notes
The wall drops very deep, so plan gas and depth limits conservatively and stay within training and experience. Boat traffic also matters near the landing stage.
Access Restrictions
The Vorder Au entry is closed for shoreline repairs until about April 2027, and the official notice says the access zone is not reachable from land or water. When open, expect a steep walk from the peninsula parking area to the entry by the landing stage.
Legal Notes
Official notices describe the Vorder Au shoreline wall as unstable and part of a renovation zone, so do not treat the lake entry as open until the closure is lifted.
Local Intel For Halbinsel Au
Community notes to help plan your visit.
Scuba Diving
A shore-entry wall dive with a steep profile, cracks, crevices, boulders, and small caves or chimneys that suit experienced freshwater divers.
Freediving
Not a baseline freedive site; the steep wall and depth make scuba the practical choice when the site reopens.
Snorkeling
Snorkeling is limited to the shoreline approach and is not the main draw; the site is built around the underwater wall.
