Les Arcs covers 200 kilometres of piste across 122 runs, from 1,200 metres at Villaroger to the 3,226-metre Aiguille Rouge, a vertical drop of 2,026 metres. The grading is gentle on paper, with 52% beginner, 35% intermediate, 10% advanced and 3% expert, so mixed groups can ski together without much friction. Most of the skiing faces north and is stacked above four purpose-built villages plus Peisey-Vallandry, so you pick a sector and work across it. Gondolas, six-seaters, two trams and a funicular keep things moving, and the lower woodland slopes stay skiable when the high ground is closed in.

The Aiguille Rouge descent is the showpiece, a run of around 7 kilometres and more than 2,000 vertical metres down to Villaroger, with its upper pitches now graded black. Below the Varet gondola the Lanches and Crêtes pistes form one long mogul field for strong legs. Arc 2000 suits confident skiers, with reds, blacks and off-piste close to the lifts, while the forests around Arc 1600 and Peisey-Vallandry give cover in flat light. Freeriders can follow an off-piste guide to Aiguille Rouge lines, ideally with a local guide. Intermediates and families will cover the most ground here.

Les Arcs opened 13 December 2025 and closes 26 April 2026, delivering a 19-week season typical of Tarentaise high-altitude resorts. The 2025-26 winter follows the pattern of mid-December starts and late-April closures, with occasional November weekend operations for early-season ski touring when snowfall permits. The funicular and main gondolas typically begin services by late November for autumn access to Arc 1600 and 1800 restaurants before full resort opening.

The domain receives an average 383 centimetres of annual snowfall with December averaging 76 centimetres and January peaking at 102 centimetres according to historical data. Summit snowpack at 3,226 metres typically exceeds 3 metres by mid-season, whilst base depths at 1,200 metres maintain 50-80 centimetres through north-facing exposure and snowmaking coverage across 43 kilometres of piste. Seventy per cent of terrain above 2,000 metres ensures reliable conditions from opening through April, with the Aiguille Rouge and Grand Col remaining skiable into late spring whilst lower west-facing slopes around Arc 1600 require morning skiing by March.

January through March delivers optimal powder conditions with February averaging 83 centimetres and 2.7 snowy days per week at mid-mountain elevation. Early December and late April offer quieter periods with shorter lift queues, though December's snowpack builds gradually and requires checking base-area coverage. March combines reliable snow depths with increasing sunshine hours—averaging 18 sunny days according to Paradiski statistics—making it popular for families. Spring skiing from mid-March sees softer morning snow and afternoon slush on sun-exposed terrain, whilst high runs retain good coverage through closing day.

The European Film Festival occupies the opening week from 13-20 December, screening over 100 films across Arc 1800 venues and attracting cinema professionals to the slopes. The Launchpad freestyle competition runs annually at Arc 2000, featuring European Big Air qualifiers with French national team riders. Speed skiing demonstrations occasionally use the Flying Kilometre track above Arc 2000, though the slope remains closed to public access. Weekly events include torchlight descents, live music at La Folie Douce from 3pm daily, and the resort operates limited night skiing on 2 kilometres of floodlit piste near Arc 1800.
