The trail starts at the lake and initially runs along the shore. Then it turns right and changes from S0 to S1 and then a little later to S2. Very fun. If you do the loop clockwise, you have to ride the trail outwards.

The Černé jezero (German 'Black Lake') is the largest glacial lake in the Bohemian Forest. It is located on Czech territory in the town of Železná Ruda (Cadastral Hojsova Stráž) and is the largest natural lake in the Czech Republic. It is framed by the 320 meter high Jezerní stěna rock face. The bedrock is mica slate, covered by a nine meter thick layer of mud that has formed over millennia from the pollen of the surrounding trees.

The lake is also oligotrophic, meaning it is low in nutrients, which contributes to its clear yet dark hue.
