Oberer Stinkersee, Salt lake in Illmitz, Austria.
Oberer Stinkersee is a shallow salt lake within Lake Neusiedl National Park marked by high salt concentrations that create a specialized environment. The water body sits in a basin formed by natural processes and is made accessible to visitors through observation towers.
The lake basin separated from Lake Neusiedl through natural processes when wave action created a dike along the eastern shore that isolated the water. This separation created a distinct saline environment that differs from surrounding water systems.
The lake serves as a working research site where scientists study specialized communities adapted to saline water. You can observe research activities and learn how these ecosystems function in practice.
Two observation towers offer good vantage points for watching water birds, especially during spring and autumn migrations. The best time to visit is during these transition seasons when migratory birds pass through the area.
The water body experiences regular changes in water levels and occasionally dries out completely, which alters its mineral composition. These extreme conditions allow organisms to thrive that can survive nowhere else.
