The lake's high peat content gives the water a dark, almost black appearance, leading to the name 'Schwarzsee' or Black Lake.
It is considered one of the warmest swimming lakes in the Austrian Alps.
The surrounding landscape is designated as a protected natural area to preserve its moor ecosystem.
The lake contains a variety of fish including pike, carp, and tench, making it a popular destination for sport fishing.
In winter, if temperatures remain low enough, the surface freezes, allowing for ice skating and winter walking.
Schwarzsee is a moor lake located near Kitzbühel known for its exceptionally dark, peat-rich water which warms significantly faster than neighboring alpine lakes. The water has a high iron content, which contributes to its distinct deep, murky appearance and therapeutic reputation. It occupies a basin shaped by the retreating Kitzbühel glacier during the last ice age. The shoreline is characterized by dense coniferous forests and protected moorlands providing habitats for rare plant species. A circular walking path encircles the entire lake perimeter, offering views of the Wilderkaiser mountain range. The lake is one of the warmest in the Tyrol region due to the heat-absorbing properties of its organic peat sediment.
The wooden boardwalk pier on the northern edge of the lake, looking back toward the Wilder Kaiser massif.
Walk the entire perimeter loop, which takes approximately 45 minutes at a steady pace.
Bring water shoes if you prefer to avoid the soft, peaty sediment on the lake floor when entering the water.
Visit during the shoulder season to experience the surrounding forest trails without heavy tourist traffic.
Assuming the water is clear or blue like glacial lakes; the dark color is natural and intentional.
Public swimming areas are accessible during the warmer months, typically May through September; the lake is generally inaccessible for swimming in winter.
Respect the protected moor zones by staying on marked paths; avoid using soaps or shampoos in the natural water.
