Runal Péra Trun is a ski area in Switzerland. It sits at about 986 m above sea level. The mapped ski area covers about 0.8 km². Within 2.5 km of the centre, the map shows 15 marked runs and 1 lift, totalling about 3.8 km of piste. Over the last three winters the ERA5 reanalysis gives it 310 cm of snowfall a season, 439th (tied) of the 3,112 ski areas we measure worldwide. The model runs well below what resorts report, so the ranking is the meaningful part rather than the centimetre figure. The nearest city of any size is Luzern, about 63 km away. 272 other ski areas lie within 120 km. Snow figures and the Powder Score are recalculated every day.
Elevation of the ski area’s centre point, taken from a digital elevation model. It is not the base-to-summit range.
We do not show a snow depth here. The weather model we use reports snow lying on the ground — it knows nothing about grooming or snowmaking, and it is not the base depth a ski area publishes. In Japan we can check our figures against 234 weather stations. Outside Japan there is nothing to check them against, so we do not print a number we have not verified.

Runs and lifts
Counted from the runs and lifts drawn on OpenStreetMap, within the boundary of the ski area. These are not the resort’s own published figures.

The shape of the mountain
Which way the slopes face
80% of the vertical on the runs descends to the north or east. Those slopes get the least sun, so the snow lasts longer.

How much snow it gets
Measured by us across 3,112 ski areas by one identical method. These are not the resort’s own published figures.
Compared with what is nearby
Within 50 km straight line. Measured the same way, so the ranks compare directly. Ski areas a few kilometres apart share a weather grid cell and can return the same figure.

| Brigels Waltensburg Andiast | 10 km | 310 cm | 439 |
| Obersaxen-Mundaun | 13 km | 255 cm | 705 |
| Vals 3000 | 20 km | 255 cm | 705 |
| Campo Blenio - Ghirone | 20 km | 291 cm | 524 |
