St Moritz Corviglia covers 155 kilometres across 36 runs, falling 1,322 vertical metres from the 3,057-metre summit of Piz Nair to the village at 1,735 metres. Intermediates hold the biggest share at 51%, with 27% beginner, 15% advanced and 7% expert. The wide, sunny slopes suit long, fast cruising, and the uphill network mixes two trains, two aerial trams, a gondola and a stack of quad and six-seat chairs. The area is part of the Ikon Pass, which adds to the traffic in peak weeks.

Piz Nair is the focal point, with the Corviglia sector below it serving long blues and reds above the Engadin lakes. Freeriders can leave the summit by the western descent or head into the Val Suvretta, and a guide is sensible for either. Groomed expert terrain is limited, so skiers chasing steep pistes may find the network tame. St Moritz suits confident intermediates and strong cruisers who value sunshine, scenery and a polished resort, and who do not mind paying for the privilege. Lunch stops are plentiful and well placed.

The 2025-26 season operated 22 November to 5 April, spanning 19 weeks across early winter through spring closure. Corviglia typically opens late November with snowmaking support across 110 kilometres of piste, closing early to mid-April depending on snow cover and visitor demand. High-elevation terrain above 2,500 metres extends the operating window compared to lower Swiss resorts, with Piz Nair holding snow into April most seasons. The resort averages 264 centimetres annual snowfall, with December through February delivering the heaviest accumulation at 64-67 centimetres per month.

Snow reliability benefits from 3,057-metre summit elevation and extensive snowmaking infrastructure covering roughly two-thirds of marked terrain. Average mid-season depths reach 108 centimetres at summit and 44 centimetres at base, with March historically offering the deepest coverage at 136 centimetres high and 50 centimetres low. South-facing slopes receive strong sun exposure, creating firm morning corduroy followed by softer afternoon conditions from January onwards. The Engadin's dry continental climate produces 300-plus sunny days annually, though precipitation when it arrives typically falls as snow above 2,000 metres through March.

January and February deliver peak powder conditions with cold temperatures and mid-winter storms, whilst March balances snow quality with longer daylight and warming trends. Early December and late March offer quieter slopes and discounted accommodation, ideal for skiers prioritising empty pistes over guaranteed fresh snow. November opening depends on early-season snowmaking, with limited terrain until December storms fill in coverage. April spring skiing concentrates on north-facing runs and higher sectors, with afternoon slush developing below 2,200 metres as sun intensity increases.

The Snow Polo World Cup takes place late January on the frozen lake below the resort, whilst White Turf horse racing runs three Sundays in February, both drawing international crowds. The Engadin Skimarathon cross-country race typically occurs early March, filling valley accommodation. Corviglia does not offer night skiing, though neighbouring Corvatsch operates Switzerland's longest illuminated piste (4.2 kilometres) on Friday evenings. The season calendar favours mid-winter through early spring, with January to March representing optimal timing for snow quality, coverage and operational consistency.
