Le Grand Massif links Flaine, Samoens, Morillon and Les Carroz across 265 kilometres of piste and 149 runs, with a vertical of 1,783 metres from 697 metres to 2,480 metres. Sanity grades the area at 51% beginner, 36% intermediate, 9% advanced and 4% expert. The low valley base at Samoens and Morillon means the area depends on snow cover lower down, while Flaine sits much higher. A wide mix of lifts, including 25 T-bars, 11 six-seaters, eight quads and seven gondolas, ties the four villages together into a single circuit.

Skiers can follow the long Cascades run, a 14 kilometre blue from Flaine toward Sixt, which is among the longest in Europe. The Tete du Pre du Saix has steeper pistes that open into fast cruising lower down, and the Combe de Gers is a well-known freeride descent with about 800 metres of vertical. Flaine's modernist village sits right on the slopes at altitude, while Samoens offers a traditional village base. Beginners and intermediates will spend most of their time on wide pistes, and freeriders should take a local guide. It is a good fit for families and mixed groups.

The 2025-26 season runs from 6 December 2025 through 19 April 2026 at Flaine, with Les Carroz and Samoëns operating 13 December to 12 April, Morillon 20 December to 6 April, and Sixt 20 December to 8 March. The staggered calendar reflects elevation differences, with higher Flaine benefiting from earlier snowfall and prolonged spring coverage. Typical season length spans 18 weeks at altitude and 16 weeks in valley villages. Pre-Christmas opening depends on early-December snowfall reaching the 1,600-metre snow front.

Annual snowfall averages 338 centimetres at mid-mountain elevations, with summit zones receiving significantly higher accumulation due to proximity to Mont Blanc weather systems. March historically delivers peak snowfall, averaging 41 centimetres per week, whilst February and March offer the most reliable powder windows. Average snow depth reaches 296 centimetres on upper slopes and 74 centimetres at lower elevations during the first week of April across the past 11 seasons. Snowmaking covers 109 kilometres of pistes, including a €1.5 million reservoir serving the Coulouvrier and Samoëns sectors with 35,000 cubic metres of water capacity.

February half-term and French school holidays generate peak visitor numbers, particularly at Samoëns and Morillon beginner zones. Early January and late March offer quieter slopes with comparable snow conditions, though late-season skiing concentrates above 1,600 metres as lower runs soften. Spring conditions favour morning sessions before midday thaw cycles begin. The exposed Flaine bowl maintains skiable coverage into late April, whilst tree-lined Morillon and Les Carroz sectors close earlier. North-facing aspect preserves snow quality longer than south-facing alternatives.

No major on-mountain events calendar exists, though the resort promotes local producers through the Origine Grand Massif label supporting regional artisans. Night skiing does not feature in the standard offering. The resort sells piste maps for €1, with proceeds funding reforestation projects on private forestry land. Sustainability initiatives include removing on-mountain rubbish bins to encourage waste removal to valley recycling points and an energy reduction target of 5% annually over two years.
