What kind of wildlife and flora can be observed around Černé Jezero?
Černé Jezero is home to rare species of plants and animals. You might spot arctic-alpine flora on the north-facing cliff above the lake, and rare invertebrates inhabit its waters. The surrounding spruce forests are part of the Šumava National Park, offering a chance to observe various forest birds and mammals, though many are shy.
Are there any hidden viewpoints or less-known spots around the lake?
While the main trail offers stunning views, some hikers enjoy exploring the slightly more challenging paths that ascend parts of the Jezerní hora cliff for different perspectives of the lake and the surrounding forest. Always stick to marked trails to protect the fragile ecosystem and for your safety.
What is the geological significance of Černé Jezero?
Černé Jezero is a prime example of a glacial lake, formed during the Würm glaciation approximately 10,000 to 12,000 years ago. Its unique 'black' appearance is due to the reflection of dense spruce forests and a deep, nine-meter layer of conifer pollen sediment at its bottom. It also lies on the European water divide, with its waters flowing towards the North Sea.

The most popular and easiest route to Černé Jezero starts from Špičácké sedlo, covering about 3.5 km one way. This path is relatively flat and well-maintained, making it suitable for most fitness levels. For those seeking a longer and more challenging hike, combining a visit with the nearby Čertovo Jezero (Devil's Lake) involves more demanding trails and greater distances.
Is there a circular walk available around Černé Jezero?
While there isn't a direct circular path that goes all the way around the lake's immediate shoreline due to the steep Jezerní stěna cliff, you can create circular routes by combining trails in the broader area. For instance, a popular option is to hike to Černé Jezero and then continue to Čertovo Jezero, returning via a different path to Špičácké sedlo or Železná Ruda, forming a longer loop.
