Alpenaquarium Grüblsee

High in Austria's green Styria, the Alpenaquarium Grüblsee bills itself as the highest diving center in Europe — a spring-fed alpine lake where divers share the water with 14 different species of freshwater fish. All types of trout and char live here, alongside more than a dozen sturgeons and housefish, including a striking albino sturgeon that draws underwater photographers back again and again.

What you'll find below the surface

Because the lake was created artificially, feeding and petting the fish is one of the main attractions — a genuinely hands-on experience. An underwater adventure garden dotted with figures gives you something new to discover on every dive, making this a rewarding spot for both curious beginners and photographers.

As a PADI Resort with 4 PADI instructors, the center offers PADI Scuba Diving, Freediving, Snorkelling and EFR first aid. It sits right on the waterfront with a retail shop, parking and equipment rental, and staff speak English, Spanish and German. A small, cozy inn serves seasonal local food lakeside.
