The starting point at Chantarella above St. Moritz can easily be reached by funicular from the centre of St. Moritz. Take the winter hiking trail through a fairytale winter forest and past the television tower to Alp Laret. From there the forest thins out and the view down to the Engadin and towards the Bernina Pass opens up more and more. The path climbs steadily and gently past beautiful benches into the Corviglia ski area and to Marguns. In Marguns the gondola can be taken back down to Celerina.
