Getting there:

The closest airport is Zürich. Klosters is two-and-a-half hours by train, with a change in Landquart.

If you decide to rent a car, take the Zürich-Chur road as far as the Landquart/Davos exit. The drive from Landquart to Klosters is through the narrow valley and passes through Kublis before arriving at Klosters-Dorf and then Klosters. The distance from Zürich is about 90 miles.
