Val d’Isère has one of the longest ski seasons in the Alps, lasting from the end of November to the beginning of May. That’s because it has some of the highest skiing, with slopes going up to 3,400m. On top of that, it has one of the most advanced snowmaking facilities in Europe. It really is one of the best snow-sure resorts in the Alps and this is ultimately the reason for its popularity.
Mid-January is popular with Brits looking for a bargain. February high season it’s popular with the French. March and April can be superb, as longer days mean spring skiing and après on the slopes.
