The climb from Hägendorf to Langenbruck over the Teufelsschlucht is a highlight in itself, and the further climb to the Chilchzimmersattel is the masterpiece. Good road surface, but gradients of up to 15% make the wonderful views hard-earned!

A very tough climb from both sides, with gradients in some places well into the double figures, but the views during the ride and from the saddle are phenomenal. The World War I Fortification Memorial Trail is also recommended.
