At 3,303 metres, Corvatsch tops out higher than almost anything else in the St Moritz region, and the snow reflects it, with 7.6 metres a year keeping the slopes dependable late into the season. The sporty Upper Engadin mountain covers 120 kilometres of piste across 26 runs, with 1,506 metres of vertical from 1,797 metres. Intermediates dominate at 74%, with 11% beginner, 10% advanced and 5% expert. Terrain suits confident skiers who want sustained, open descents rather than nursery slopes, and three aerial trams plus a handful of chairs keep the large area linked together.

The Hahnensee run, known as the Königsabfahrt of the Engadin, is a black descent of about 9 kilometres to St Moritz Bad and is the signature piste. Freeriders head for Fuorcla Surlej, reached from the top of the Corvatsch cable car, which offers around 1,000 metres of vertical through wide powder slopes and steep couloirs; this is serious terrain needing proper gear and a guide. Murtèl has wide rolling blues for lower intermediates, and Friday night skiing lights up the longest floodlit run in Switzerland. Best for strong intermediates and advanced skiers, with limited options for beginners.

The 2025-26 season opened 22 November and runs through 26 April, spanning five months of lift-served skiing. Corvatsch typically operates one of the Engadin's longer seasons, with north-facing aspects and high elevation preserving coverage into late spring. Early-season openings in late November align with the resort's 3,303-metre summit elevation advantage.

Snowfall averages 760 centimetres annually at upper elevations, though recent seasons show variability. The 30-year average sits near 170 centimetres, whilst the 2023-24 season delivered only 80 centimetres. North-facing exposure and glacier presence help maintain base depths above 100 centimetres during peak winter. Limited snowmaking supplements natural accumulation on key runs including the night skiing route.

January through March delivers prime conditions, with February offering the deepest snowpack and coldest temperatures for powder preservation. April extends the season on upper slopes, where spring corn develops reliably on sun-exposed aspects. Powder can linger for days in shaded sectors given Corvatsch's quieter midweek traffic compared to Corviglia.

Friday night skiing runs 7pm to 1am December through January and 7pm to 2am February through April on the 4.2-kilometre illuminated descent. The Corvatsch Park terrain features and halfpipe operate throughout the season. No summer glacier skiing operates despite the summit's elevation. Mid-November through early May represents the reliable window for snow conditions.
