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.
