How we built this ranking
We include ski areas that are linked on skis, or sold with a single lift pass, and rank them by the kilometres of marked pistes each area announces. These figures are declared by the ski areas themselves: each one measures its pistes in its own way, and two reliable sources can give different values for the same area. Where that happens, we say so. Cross-border areas are included when a large share of their pistes lies in France.
