The mind-bogglingly sheer, breathtakingly fast Streif downhill course lures hard-core skiers to Kitzbühel – even experts feel their hearts do somersaults on the Mausefalle, a notoriously steep section with an 85% gradient. Jumps reach up to 80m and speeds can top 140km/h, which is sheer insanity on skis. One of the most terrifying World Cup courses, it's the stuff of legend.

Ski it at least once if you dare.
