Starts in the wide Rhonevalley at the point,
where the road from Ulrichen to the pass crosses the river.
Soon there is a steep part (7-10%) of about 3 km long
ending in the straight and narrow Agenetal.
The first part in this valley is the only easy part of the climb.
A kilometer later the road starts to become steeper again
and this sets the stage for the remaining 800 elevation meters,
which are relentless with a slope of mostly 9 or 10%.
The award must be a magnificent landscape
if I believe the pictures that can be found on the Internet
(I personally only saw clouds).
The low traffic density makes the Nufenenpass very suitable for race bikers.
