The gateway airport is Zürich International Airport and there are numerous flights here, both scheduled and charter, from around the world. There is at least one train an hour departing for Lenzerheide, with a change at Zürich, and then Chur, from where you need to take a Postbus to either resort (2 hours, 30 minutes).
The quickest route bypasses the cities of Reims, Metz, Strasbourg, Basel, Zürich and Chur. From Chur, take route 3 to Valbella then Lenzerheide. From Zürich Airport, drive through the city and head for the (A-3/13) Chur autobahn. Circle Chur and take the Waffenplatz Strasse/route 3 for the resorts.
