Liechtenstein maintains a complete customs union with Switzerland and hence does not issue its own visas: It is represented by Switzerland in embassies around the globe. If you can enter Switzerland, you can enter Liechtenstein, for decades there have been no border formalities needed for crossing between the two countries. In essence there is nothing more than a sign announcing your arrival in Switzerland or Liechtenstein when you cross the Rhine or the land border, similar to the situation at smaller border crossings in many EU nations, Austria/Germany/France/Italy etc. Stamp hunters can, however, get an authentic Liechtenstein entry stamp in their passport at Vaduz's tourist office for 3.00 Swiss franc CHF or €2.00. The stamp is not available at the Liechtensteinisches Landesmuseum, the tourist office is the only place that you can purchase the stamp.
Liechtenstein has no airports due to the size of the country. You can take a flight to ZÃ¼rich Airport 115 km. Although the airport was the only major airport near Liechtenstein, there were some limited services from Vienna to St. Gallen-Altenrhein Airport 53 km by Austrian Arrows (http://www.aua.com). There was also a private airport in Bad Ragaz, very near the country. Another popular point of entry is through Friedrichshafen in Germany, which is served by low-cost airlines.
Liechtenstein's Prince has a heliport in the Southern low lands.
The Swiss Autobahn A13/E34 runs along the swiss side of the Rhine River, the border between Switzerland and Liechtenstein. There are several access points that cross the Rhine into Liechtenstein, the two that are most commonly used are the bridge crossing into the southern town of Balzers and the crossing into Vaduz. Parking in Vaduz is easy, with a large parking garage located below the Kunstmuseum. Driving in Liechtenstein is relatively safe, but extra care should be taken on narrow and winding mountain roads. Speed traps are everywhere!
