Grandval
Grandval is a ski area in Switzerland. It sits at about 1,119 m above sea level. The mapped ski area covers about 1.9 km². Within 2.5 km of the centre, the map shows 5 marked runs and 1 lift, totalling about 5.1 km of piste. Over the last three winters the ERA5 reanalysis gives it 61 cm of snowfall a season, 2694th (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. 199 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 marked runs and lifts on the map, within 2.5 km of the centre of the ski area. These are not the resort’s own published figures.
By difficulty
Lift types
- T-bar1
Source: OpenStreetMap (ODbL 1.0). How finely ski areas are drawn varies by region, so treat the counts as indicative. Difficulty uses the European grades, which do not map onto North American green / blue / black.
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.

| Grenchenberg | 5.2 km | 61 cm | 2694 |
| Röti | 8.4 km | 51 cm | 2797 |
| Malleray - Les Orvalles | 12 km | 89 cm | 2352 |
| Hohe Winde – Beinwil | 16 km | 56 cm | 2745 |
