St Moritz is a high-end Engadin resort whose local mountain, Corviglia/Piz Nair, offers 155km of groomed pistes and direct access from town by funicular and cable car. Corviglia reaches 3,057m and is particularly strong for intermediates, with extensive blue and red terrain, polished mountain restaurants and reliable high-altitude conditions. The wider Upper Engadin adds major ski areas at Corvatsch/Furtschellas, Diavolezza and Lagalb, giving advanced skiers and repeat visitors much more variety. Those sectors are separate rather than one continuous lift-linked domain, so exploring the full region requires local transport. St Moritz itself is refined and service-rich, with grand hotels, restaurants, shopping and a remarkable winter-sports heritage. The obvious trade-off is cost: accommodation and dining are among the most expensive in the Alps.
