Klosters and the Madrisa
A gentle, sunny mountain above a quiet, pretty village, the clear beginner winner.
Klosters wins because the Madrisa is everything a learning hill should be: sunny, gentle, uncrowded and self contained, with a gondola from the village edge and a ski school that has taught generations of children, including royal ones. Nothing up there intimidates, and the wide blues let you progress without ever feeling hunted by faster traffic.
It beats Davos because the village is calmer and prettier, and because the Madrisa is a better shaped mountain for first weeks than anything on the Davos side. The catch is the quiet evenings; if you want busy apres, you are in the wrong ranking anyway.
