By Train Or Bus
The easiest way of getting to Liechtenstein by train is to travel to Sargans or Buchs in Switzerland, or Feldkirch in Austria, and then take a connecting bus to Liechtenstein.
ÖBB, the Austrian federal railway company, runs a very limited train service from Buchs SG station in Switzerland, via Schaan-Vaduz station near Schaan to Feldkirch in Austria. Trains only run during weekday peak hours, which makes buses far more convenient.
Fast trains from Zurich and many international train services serve Sargans during the day. Consult the SBB timetable (http://sbb.ch/en/index.htm) to find out what'll be quickest when you're travelling. There are lockers at Sargans station so you can leave your luggage there. The link (http://mct.sbb.ch/mct/en/...) provides a plan of the station showing the lockers and where to catch the bus from.
Liechtenstein buses are a distinctive light green colour. Tickets can be purchased from the driver.
Bus route 11 runs from Sargans railway station to Feldkirch railway station via central Vaduz and Schaan. It leaves from outside each station approximately every 30 minutes during the day. A fare to Vaduz is 5.80 CHF from Sargans. Consider buying a whole network one-day pass 12 CHF or one-week pass 24 CHF if you are making multiple journeys.
Bus route 12 runs every 15 minutes from the train station at Buchs a town on the Swiss side of the border to Liechtenstein to Schaan, from where connecting buses run to Vaduz. Tickets can be purchased on the bus for 3.40 CHF and it only takes about 10 minutes to Schaan and another 5 to Vaduz.
Liechtenstein Bus route 14 is a more direct service from Feldkirch to Vaduz.
Liechtenstein is a member of the Schengen Agreement.
There are no border controls between countries that have signed and implemented this treaty - the European Union except Bulgaria, Croatia, Cyprus, Ireland, Romania and the United Kingdom, Iceland, Liechtenstein, Norway and Switzerland. Likewise, a visa granted for any Schengen member is valid in all other countries that have signed and implemented the treaty. But be careful: not all EU members have signed the Schengen treaty, and not all Schengen members are part of the European Union. This means that there may be spot customs checks but no immigration checks travelling within Schengen but to/from a non-EU country or you may have to clear immigration but not customs travelling within the EU but to/from a non-Schengen country.
Please see the article Travel in the Schengen Zone for more information about how the scheme works and what entry requirements are.
Despite the country being a member of the Schengen Agreement and the EEA, Liechtenstein is not a member of the EU. Therefore, travellers entering Liechtenstein from Austria and vice versa are subject to non-systematic customs controls, despite the fact that there are no immigration controls.
Liechtenstein, however, maintains a complete customs union with Switzerland and is represented by Switzerland in embassies around the globe. Since 1923 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 €2.50. The stamp is not available at the Liechtensteinisches Landesmuseum; the tourist office is the only place that you can purchase the stamp. Be aware that such memorial stamps may render your passport 'falsified' in the eyes of Finland's consular and border control officials.
Liechtenstein has no airports due to the size of the country. You can take a flight to Zürich Airport 115km. Although the airport was the only major airport near Liechtenstein, there were some limited services from Vienna to St. Gallen-Altenrhein Airport 53km by Austrian Arrows. 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 and Turkish Airlines.
There is a heliport in Balzers owned and operated by Swiss Helicopter. From there, one can take scenic flights around the country or book shuttle flights, e.g. from or to Zurich airport. The latter being private charter flights, not scheduled ones, cost around 4000 CHF for up to five passengers.
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!
