Alatsee is a rare meromictic lake, meaning its water layers don't mix. This creates a fascinating stratification, including a vibrant red 'blood cloud' layer of purple sulfur bacteria at depths of 15-18 meters. Above this, the water is crystal-clear and oxygen-rich, supporting diverse life. This unique natural phenomenon, combined with its serene setting, sets it apart.
While the upper layers of Alatsee are popular for swimming due to their clear and refreshing water, diving in the lake has been prohibited since 1983, with exceptions only for scientific research. This is partly due to the toxicity of organisms in the deeper layers and the potential release of hydrogen sulfide, which can be dangerous.
Parking is available near Alatsee, but it tends to fill up quickly, especially during peak season and on weekends. Arriving before mid-morning is strongly recommended to secure a spot. The lake is accessible via various trails, including a popular route from Weißensee and a more challenging ascent from Füssen.
