The lake's intense blue color is a result of light refraction caused by the high transparency and specific mineral composition of the water.
The entire lake basin was formed by a rockslide from the Kandertal mountain range thousands of years ago.
The water temperature remains constant at approximately 8 degrees Celsius year-round.

Blausee is a small, spring-fed lake located in the Kander Valley of the Bernese Oberland, renowned for its intense blue water color caused by light scattering. The lake is part of a 20-hectare private nature park protected by a forest preserve. An on-site organic trout farm operates at the lake, supplying the associated hotel and restaurant. The lake bed is characterized by naturally fallen rock formations from a prehistoric landslide. Visitors can access the lake via a short, forested walking path within the park grounds. A glass-bottom boat is available for lake excursions, providing a direct view of the underwater logs and trout. The site includes a wellness hotel with spa facilities overlooking the water. The surrounding park features walking trails, a fireplace for grilling, and a playground.
The wooden bridge located at the edge of the lake provides the clearest view of the turquoise water and the submerged logs.
Wear sturdy walking shoes to navigate the uneven terrain on the forest trails surrounding the lake.
Purchase your park entry ticket online in advance to avoid queues during peak summer weekends.
Visit the trout farm area early in the morning to see the fish feeding activity.
Do not attempt to swim or wade in the water, as the lake is a protected nature reserve and the water temperature is dangerously low.
The nature park is open year-round, though heavy snowfall may limit access to specific forest trails in winter.
Stay on marked paths to protect the sensitive forest floor; swimming in the lake is strictly prohibited.
