Read about traveling by car and public transport in Graubünden.
The Rhaetian Railway
Graubünden has its own railway company: the Rhaetian Railway (RhB). The excellent narrow gauge rail network stretches out to most corners of Graubünden. We find the red trains of the RhB a pleasure to travel with. In additional to the trains, there are buses and cable cars which go where trains don't.
The flagship of the RhB is the Bernina Express from Chur to Tirano.
Traveling by car
Because of the excellent public transport, a car is not a necessity the explore Graubünden. Please note that if you plan to drive in Winter, many passes will be closed and you will have to use a car train to cross the mountain range between the Engadine and the north of Graubünden, and also to enter Graubünden from the east (Oberalp Pass). Also, some main roads in the higher vallies may be covered with snow, so your vehicle and driving skills need to be up to those conditions.
