Getting there:

The closest airport is Zürich. From there you can take a train to Chur, where you must change for a postbus to Flims, Laax or Falera. The entire trip takes about three hours.

If driving, take the main road to Chur and continue until you see signs for Flims to the right. Driving time is about two hours. Do not try to approach Laax, Falera and Flims from the west—the Oberalp pass is closed in winter.
