Questions

What is the steepest ski run in the world?

Of the marked in-bounds runs we track, Big Couloir in Big Sky is the steepest, with a maximum gradient of about 119% (50°). Off-piste couloirs can be steeper, but they are not marked runs.

What is the difference between gradient in percent and in degrees?

A 100% gradient means the slope drops one metre for every metre forward, which is 45°. Percent grows much faster than degrees near the top of the scale: 70% is about 35°, 50% is about 27°. Resorts like to quote percent because the number sounds bigger.

How steep is a normal black run?

Most black runs in the Alps peak somewhere between 40% and 60% (roughly 22° to 31°). The runs on this list go well beyond that, usually over 35° on their steepest pitch.

Gradients are the steepest short pitch of each run, as published by the resort or measured by independent sources. Sources often disagree by a few percent, and each run page lists the ones we used.
