It is best known as a snow sure ski resort. Together with neighbouring Val d'Isère, it forms the "Espace Killy" ski area. The proximity of two resorts offers one of the most seamless links between ski areas in Europe, in effect creating a single skiable area of over 300 km piste. Whilst not the largest ski area in the Alps, the level of integration between the two resorts has the effect of making it feel as one, often described as feeling like one of the largest single ski areas as a result.
