Haggenegg climb, from Schwyz, it's one of the hardest climbs I've ever done. 6.7 Km with an average of 13 %. Not exceptionally steep on average, but for 6.7 Km is a lot. Also the climb to Mostelegg is not easy but is much more shorter (from the fork of the road). Finish is in the ski resort Mostelberg
