The Hüsler scale, designed by Eugen Eduard Hüsler, author and photographer born in Switzerland, graduates the ferrata pathways in five difficulty levels. For this, Hüsler devised the Hüsler cross, a cross in which the four most important aspects that define an itinerary are scored from 1 to 4: required strength, resistance, mountain experience and psychological aspects. The result on the cross will indicate at what level of difficulty we should catalog the difficulty of the via ferrata.
The 6 difficulty levels classified from K1 (easy) to K6 (extremely difficult). The letter K, as in the distinction carried by carabiners for via ferrata, refers to the German word "Klettersteig" (via ferrata).
For the difficulty levels, Hüsler uses the same cross in which the four most important aspects that define an itinerary are scored from 1 to 4: required strength, endurance, mountain experience and psychological aspects. The result on the cross will indicate at what level of difficulty we should catalog the difficulty of the via ferrata.
- K1 (easy)
- K2 (bit difficult)
- K3 (something difficult)
- K4 (difficult)
- K5 (very difficult)
- K6 (extremely difficult)
