Biggest ski areas in the Alps by piste kilometres

Last reviewed 21 October 2026. Figures come from our own resort pages on resortslopes.com and are compared with operator pages where we could open them.

The largest Alpine ski areas by published piste kilometres are Verbier / 4 Vallées (410 km), Sestriere (400 km) and Zermatt (360 km). That is the ranking in our own dataset, built from the resort pages on resortslopes.com. It is a useful guide to scale, not a precise measurement, because operators do not count kilometres the same way.

Which are the 10 biggest ski areas in the Alps?

The table ranks Alpine areas by the piste kilometres published on our resort pages. Where we link a resort name, you can open its page for more detail.

Just outside the top ten in our dataset are Serfaus-Fiss-Ladis (214 km), Val Gardena / Seiser Alm (175 km), and the Courchevel, Méribel and Val Thorens group (150 km each in our listings). Several of those belong to larger linked regions, which is exactly why the next section matters.

Why do operators count piste kilometres differently?

There is no universal rule for what counts as a kilometre of piste. The main differences we see:

• Linked region or single mountain. Some figures cover an entire interconnected lift-pass area; others describe one resort or one mountain within it.
• Ski-in/ski-out routes. Some operators include the routes that bring you back to a village, others count only the main marked pistes.
• Ungroomed itineraries. Marked but ungroomed routes may be included in one figure and left out of another.
• Rounding and updates. Operators round figures, and new lifts or links change them from season to season.

What does each piste-kilometre number include?

We opened several operator pages to compare them with our figures. This is what each page says, and just as importantly what it does not say.

So where we could compare, the figures agree closely (Arlberg 300 against 301 km, Alpe d'Huez 250 against more than 250 km, Verbier 410 km on both), while for Davos Klosters and Zermatt the pages we opened published no total. For Sestriere and the other areas, check the operator's current page.

Where does Grandvalira fit?

Grandvalira, with 215 km in our dataset, is in Andorra in the Pyrenees, not the Alps, so it is not in the ranking above. It is a reminder that very large linked ski areas exist outside the Alps too.

Is a bigger ski area better?

Piste kilometres are one measure of scale, and only one. Without claiming more than the numbers allow:

• Variety. A larger linked area generally offers more runs and more ways to vary a day without repeating a piste.
• What the number does not show. Kilometres do not tell you about snow conditions, queues, the balance of easy and hard runs, or where the lifts actually take you.
• Travel time. In a very large area, reaching distant sectors can take a good part of the day, depending on the lift links and your pace.
• Your own level. A beginner or a family may be better served by a smaller area with well-placed easy runs than by the longest total.

In short, bigger means more choice on paper. Whether it means a better trip depends on your level, your dates and what you want from the days. Treat every figure here as a starting point for your own research rather than a verdict, and remember that the operator's current map is the final word on what is open and linked in a given season.

How should you use these numbers when choosing?

Use the ranking to shortlist, then read the operator's own current figures and piste map. For a step-by-step approach, see choosing your first ski resort and piste difficulty explained. Resort pages such as Verbier / 4 Vallées and Zermatt give more detail on each area.
