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.

Saint-Michel Pass

Highlight • Mountain Pass

On the pass, there was, among other things, a chapel, a source and a kind of altar with a cross, the latter being still more or less intact on the way.
