The region is centred on artificial reefs across multiple lakes, ranging from purpose-built dive towers to a themed underwater petting zoo at the Grüblsee site itself. Schwarzlsee combines an artificial reef with a submerged wreck, and the MS St. Wolfgang offers a dedicated wreck dive at a consistent shallow depth. All sites are shore-entry, so no boat is required.
Yes. Every top site in the region is rated beginner level, with shallow depths and calm, current-free conditions throughout. The artificial structures and controlled lake environments make the sites particularly well suited to newly certified divers or those on training dives. Tauchsport ScubaProfis operates locally and can provide guidance on site.
Snail, Sun Perch, Pike, Pike Perch, and Common Perch are all commonly observed across the lakes. Carp, Wels Catfish, Chub, and the Western Tubenose Goby appear occasionally, and Sturgeon has also been recorded. Trout, Brown Trout, Rainbow Trout, and Freshwater Crayfish have been sighted at select sites as well.
All top sites are shore-entry dives, meaning you can enter directly from the lake bank without a boat. This keeps logistics simple and costs low. The sites are spread across different lakes in Styria, so divers typically travel between them by road to explore the full range the region offers.
