A cute little waterfall that flows down a small rock face. You can cross to the other side via a ford, though during heavy rain, you may have to wade through the water.

Probably a bridge in winter to more easily cross the only, heavily used access road to the ski resort. In summer a resting place for cows. Surprising to see such a bridge in the middle of the forest...
