What is Piste Grading (Ski Run Difficulty)?

The colour-coded system rating ski run difficulty — green, blue, red and black in Europe; green, blue, black diamond in North America.

Ski runs (pistes) are graded by difficulty using a colour-coded system. In Europe: green (beginner), blue (intermediate), red (advanced), black (expert), with some resorts adding orange/yellow for extreme terrain. In North America: green circle (beginner), blue square (intermediate), black diamond (advanced) and double black diamond (expert). Grading factors in gradient, width, grooming, obstacles and exposure — not just steepness. Grading is relative to each resort, and European reds are often steeper than North American blues, so caution is needed when skiing unfamiliar resorts.

In practice

Piste (ski run) difficulty grading — typically green, blue, red and black in Europe, or green, blue, black and double-black in North America — gives skiers a quick, standardized way to judge a run's steepness and difficulty before committing to it, though grading standards can vary somewhat between resorts and countries, which is why a 'red' run at one resort can feel noticeably different from a 'red' at another.

FAQ

What do the different piste colors mean?

Green and blue runs are easier, gentler gradients suited to beginners and improving intermediates; red runs are steeper, more challenging intermediate-to-advanced terrain; black runs are the steepest, most difficult, often including moguls or narrow sections.

Does piste grading mean the same thing at every resort?

Not exactly — while the general colour-coded difficulty order is consistent, grading standards vary somewhat between resorts and countries, so a run graded red at one resort might feel more like a black at another.
