Grundlsee, Alpine lake in Styria, Austria.
Grundlsee is an alpine lake in the Styrian Salzkammergut region, stretching across a large area at 708 meters elevation and forming the largest water body in this part of Austria. The lake is surrounded by mountains and fed by streams flowing down from higher peaks.
The nearby Salzofen cave holds archaeological finds pointing to human settlement dating back 34,000 years in this region. Bronze Age and Iron Age artifacts from this site show how long people have inhabited these valleys.
The lake is marked by traditional wooden boats called Plätte, which local fishermen have used for generations as part of daily life here. These boats remain a defining feature of how people relate to the water.
Several designated beach areas around the lake offer stone, sand, and grass sections for swimming, with children's playgrounds nearby at different access points. Different shoreline sections suit various preferences, whether you want to wade in shallow areas or find rocky spots.
Water temperatures reach around 24 degrees Celsius during summer months, which is surprisingly warm for a mountain lake at this elevation. This mild temperature makes swimming comfortable even at high altitude.
