Liechtenstein is easily one of the safest countries in the world, though it is not without its problems. The most common crime in Liechtenstein is of a non-violent nature, though the Principality maintains a well-equipped police force which maintains a presence on the streets. In the late 1990s, the Liechtenstein Landespolizei launched a crackdown on prostitution in Vaduz. Considering the largest cities nearby are Innsbruck and Zürich, outside of Schaan and Vaduz, the whole place can seem very rural. Drunk drivers and winter road conditions may be your only "realistic" concern. Speed limits are strictly enforced by speed cameras which will be very pricey. Don't speed, enjoy the scenery instead!
The country's beautiful scenery is also very dangerous. Cases of hikers finding themselves in difficulty are very common, and extreme care should be taken when leaving the well-marked trails. Follow local advice, read local weather forecasts newspapers in the Principality print individual forecasts for the different cities in Liechtenstein, which is beneficial because the difference in altitude often cause different weather conditions, and ensure that you have the correct equipment before setting out.
The national language is German, but the main language in everyday use is Alemannic German dialect, which Liechtenstein shares with German-speaking Eastern Switzerland, Baden-Württemberg south of Stuttgart, Germany, and Vorarlberg, Austria. Almost everyone can speak standard German when necessary, and English is also prevalent. French and Latin are also widely taught in the secondary public school system.
Internet access is available with one station at Telecom Liechtenstein immediate south of Vaduz's centre on the main road, but this is only open during business hours. Most hotels and some bars/restaurants will have net access such as in Schaan. The last real Internet cafe disappeared, because every one in the country has net access in their homes, so the local market completely disappeared and only visitors need access.
The Principality of Liechtenstein has existed for centuries as an independent state and this should be remembered. Liechtenstein is not part of Switzerland or Austria, and its citizens will not hesitate to remind you.
Remember that this is a traditional Catholic country. On Sundays, the streets are almost dead except for the tourists and the tourist shops.
Liechtensteiners are very proud of their national identity and would take offence at being wrongly labelled "German", "Austrian" or "Swiss". Those who may feel inclined to denounce the monarchy as a system of government should be advised: the prince is well loved and very popular, and he is certainly held in high esteem when discussing national politics.
