Diavolezza operates between 2093 and 3006 metres in the Val Bernina, delivering 913 metres of vertical drop across 35 kilometres of marked pistes and 10 additional kilometres of ski routes. The resort's two separate mountains, Diavolezza and Lagalb, offer 10 designated runs split 12% beginner, 65% intermediate and 23% advanced/expert terrain. The 10-kilometre Morteratsch glacier descent ranks as Switzerland's longest secured glacier run, whilst Lagalb's Minor slope holds an 86% gradient, making it Graubünden's steepest prepared piste. Sitting entirely above 2000 metres on north-facing terrain, the resort guarantees reliable snow conditions throughout its extended season.

Diavolezza caters primarily to intermediate and advanced skiers, with limited terrain for beginners beyond a small practice area at the base. The Diavolezza side features wide cruising runs and the signature glacier route past Piz Palü and Piz Bernina, whilst Lagalb delivers steeper, more technical terrain including the challenging La Rösa freeride descent into Val Poschiavo. Off-piste opportunities dominate the experience, with accessible sidecountry lines in Val Arlas and Val Minor drawing freeriders to this treeless, high-alpine environment. The resort's compact lift network means minimal crowds and quick access to untracked powder after storms.

Berghaus Diavolezza at 2978 metres provides on-mountain dining, overnight accommodation and an outdoor jacuzzi with direct glacier views. The summit station serves as base for full moon skiing events during Glüna Plaina and the Diavolezza Challenge ski touring route. Both mountains feature their own railway stations at the base, with Rhaetian Railway providing direct access via the UNESCO Bernina Line. The intimate scale and authentic mountain atmosphere contrast sharply with the busier St Moritz resorts just down the valley.

Diavolezza and Lagalb operate under local lift passes starting at CHF 38-70.50 per adult day ticket with dynamic pricing, or form part of the Upper Engadin regional pass covering Corvatsch, Corviglia and all St Moritz resorts across 350 kilometres of terrain plus free local trains and buses. The 2025-26 season runs from mid-October through early May, capitalising on the glacier's altitude advantage. This is expert-focused terrain for confident skiers seeking off-piste adventure, long cruising runs and some of Switzerland's most dramatic high-alpine scenery away from mainstream resort crowds.
