How we picked
Paris doesn't get snow but Paris gets the TGV, and that single fact reshapes which French resorts qualify as weekend-doable. Les Arcs wins on connection: 4 hours 13 minutes direct from Gare de Lyon to Bourg-Saint-Maurice on the TGV des Neiges, then the Arc-en-Ciel funicular straight up to Arc 1600. You can leave the office Friday at 6pm and be skiing Saturday by 9. Tignes and Val d'Isère share the same Bourg-Saint-Maurice arrival, with Altibus shuttles handling the last 30 kilometres. Val Thorens takes the train to Moutiers Salins and a 45-minute bus up the Belleville valley, and at 2300m guarantees snow even in lean Decembers. Courchevel uses the same Moutiers line, ideal for those who want Michelin food at 1850 without ever touching a steering wheel. Chamonix offers something different: the TGV runs to Saint-Gervais-Les-Bains then a Mont-Blanc Express climbs the valley, putting Argentiere and the Grands Montets within striking range of a Eurostar connection from London too. For drivers, Megève sits 5h30 from Paris via the A40, perfect for those who want their car for the inevitable lunch up in Combloux. These six form the realistic Paris-to-piste roster, the ones where the journey feels worth it.
