From the upper threshold, this path leads along the Deffernik and later through the beech forest to the main hiking trail. On the way to overcome some fallen trees; You can get wet shoes down the Deffernik. Wonderfully lonely here.

A lovely little lake - almost a Canadian idyll 😉 Coming by bike from Zelzna Ruda, our last stretch of the route here was closed to bikes - when it got crowded with hikers, we had to push...

Beautifully situated. The spruce forest, which has currently died due to the bark beetle, gives the lake a special mystique!
