Piste difficulty grading
Ski areas grade marked runs by colour or symbol so riders can judge, before setting off, roughly how demanding a run will be.
Overview
Marked runs at a ski area carry a difficulty grade, shown on the piste map and on signs at the top of each run. The grade is a guide to how steep and demanding the run is relative to others in that area, which is what lets a rider choose terrain that matches their level.
Grading systems are regional rather than universal: the colours and symbols used in Europe differ from those used in North America and Japan, and grades are set relative to the rest of that resort. A run graded easy at a steep, high-mountain resort can feel harder than a mid-grade run somewhere gentler, so the map is a starting point rather than a guarantee.
Key points
- Grades describe difficulty relative to the other runs at that ski area.
- Colour and symbol systems differ between regions, so a map legend is worth reading.
- A grade reflects the run as pisted; conditions change how it actually skis.
- Choosing runs within your level is the practical use of the grading system.
- Marked runs are patrolled and prepared, which is part of what the grade assumes.
