No Airport
Another thing about Liechtenstein you should know is that it has no airport. If you go to Liechtenstein, not by air for sure. This is because the country is too small and too mountainous to own an airport. You can travel to Liechtenstein via other ways, though. You can go to Zurich Airport (ZRH) in Switzerland or Vienna International Airport (VIE) in Austria and then take a train or bus to Vaduz. You can take the train from Feldkirch, Austria, to Vaduz, going four times a day. Traveling by bus is usually preferred by visitors as it is comfortable and passes through beautiful landscapes with an amazing views.
Surprisingly, you can also hike or cycle to Liechtenstein from Austria. The road goes through the historic wooden bridge, Alte Rheinbrucke. If you are traveling from Switzerland, your Swiss Travel Pass will be working for busses and museums in Liechtenstein.
