Bordered by Switzerland and Austria, the tiny principality of Liechtenstein covers an area of just 62 square miles making it the 4th smallest country in Europe after Vatican City, San Marino and Monaco. But don’t let the diminutive size fool you, Liechtenstein has the highest GDP per person in the world and is the 2nd richest country in the world after Qatar. The capital city of Vaduz owes its name to Vaduz Castle which rests on a wooded hilltop overlooking the town. The castle is the official residence of the Prince of Liechtenstein and, as such, isn’t open to the public but there are several good vantage points from the road and a variety of hiking trails nearby that allow you to enjoy a magnificent Alpine-framed view of the castle.
