Attention (!). As of June 2026, almost the entire route (except for the curves themselves) is gravel! It's small gravel and can be ridden with a road bike, but anyone who doesn't want to risk anything shouldn't go this way. Definitely don't ride downhill here.

Nice ascent D80, little traffic, partially newly gravelled road. Unfortunately, the nice signs about the pass regarding km and gradient are missing.
