The French Alps are several ski countries that share a border and not much else.
The linked domains
Les 3 Vallées is the 600 km domain in the Tarentaise: seven resorts, 169 lifts, Courchevel at one end and Val Thorens at the other. Tignes–Val d’Isère is the next valley up, 300 km and 71 lifts, formerly Espace Killy. Paradiski joins La Plagne to Les Arcs, 425 km if you buy that pass. Serre Chevalier is 250 km in the Briançonnais. Montgenèvre is a smaller domain on the Italian pass. Chamonix is a town with separate mountains. Megève and La Clusaz are village resorts in Haute-Savoie. Les Deux Alpes is high in the Oisans. Valmorel is Le Grand Domaine, not Les 3 Vallées.
How this meets 2030
Only some of those places are venues. The venue table is the filter. A domain’s size does not make it a race site. Méribel is huge and is not a 2030 venue. Le Grand-Bornand is smaller and is the biathlon site.
For the week itself, start with where to stay and getting there. For equipment, hire or the gear list.
