Superb waterfalls nestled in the woods, an ideal place to cool off and fill up with water during a hike or even during a day trip!

Is it a piece of art? Is it an artful setting for an aperitive à deux? Is it private or is it public? There's a small walking path leading up the hill.

From a protruding rock slab you have a breathtaking view of the lake and to the west - perhaps the most beautiful view of Mont Grelle. But a lot of hikers know this, so you often meet other people here.

Good point of view to be deserved, rather quiet access on foot, harder by mountain bike / Gravel
