Les 2 Alpes stretches 200 kilometres across 88 runs, climbing from 1,280 metres in town to 3,523 metres on the glacier, a vertical of 2,243 metres. Sanity grades it at 55% beginner, 28% intermediate, 12% advanced and 5% expert, so there is far more gentle terrain than the glacier altitude suggests. The lift system includes eight gondolas, 15 T-bars, seven quads and two trains, and the Jandri gondola takes riders from the village toward the high slopes. With altitude and a long season, it is a dependable choice early and late.

The glacier is the main attraction, with open, high-altitude slopes that stay in good shape when lower runs struggle. Down in the middle of the mountain, long red and blue runs wind back to the village, and the Vallee Blanche on the west side offers quieter, gentler skiing between 2,100 and 1,650 metres. Les 2 Alpes also has a strong freeride scene, with off-piste lines reached from the glacier, though these need a guide and good avalanche awareness. Beginners, progressing skiers and snowboarders will feel at home, and experts will find steeper options if they look beyond the pistes.

The 2025-26 winter season operates 29 November 2025 to 3 May 2026, delivering 156 days of lift-served skiing across the main domain. Spring skiing continues on the glacier through May with reduced operations, and the area partially reopens from mid-June to late August for summer skiing, training camps and mountain biking. October half-term openings occasionally occur on the glacier when snow cover permits, whilst ski touring extends access during closure periods. The resort's high-altitude profile and glacier reach support one of France's longest operational calendars.

Historical snowfall averages 334 centimetres annually, with the heaviest accumulations in December through February when the second week of December typically receives 54 centimetres. Elevation advantage keeps 75% of terrain above 2,000 metres, where natural snow remains reliable from early winter through late spring. The glacier holds 180 to 300 centimetres of base depth through March whilst lower slopes carry 80 to 120 centimetres, and snowmaking infrastructure supplements natural coverage on key runs including the new blue home piste. Temperatures range from minus 8 to minus 3 degrees Celsius on the glacier, with village-level daytime highs reaching 5 to 10 degrees during spring months.

January and February deliver peak powder conditions with consistent cold temperatures, whilst March and April offer spring corn snow and longer daylight for high-altitude sessions. December provides early-season access often limited to upper sectors until mid-month snowfall builds lower-elevation bases. Weekdays outside French school holidays see notably lighter crowds, and the glacier's north-facing exposure preserves snow quality through April and May when lower slopes soften by afternoon. Mornings offer firmed overnight refreeze during spring, with skiing best before midday as temperatures climb.

The Rise Festival precedes Christmas with music performances and DJ sets on-mountain and in the village, combining six-day lift tickets with concert access. January's Mad Snow Race and March's SnowZone and Snow Fest events mix skiing with entertainment, whilst night skiing on Vallée Blanche operates throughout the season. Summer glacier operations from 13 June to 30 August run 07:00 to 12:30 daily, hosting national team training, freestyle camps and the Mountain of Hell downhill mountain bike race in late June. Les Lumières de la Muzelle night trail race features 11, 16, 21 and 42-kilometre distances through winter darkness.
