Austria, one of Europe's most popular holiday destinations, attracts tourists year-round with places to visit in both summer and winter. In fact, with some of Europe's finest skiing, winter is almost as busy as summer in the spectacular mountain regions. Visitors are drawn as much for the scenic beauty of this Alpine republic's provinces as they are for splendid cities like Vienna (Wien), the historic capital, and beautiful Salzburg, birthplace of Wolfgang Amadeus Mozart. One of Europe's smallest countries, Austria is predominantly a nation of upland areas and high mountains, with the Eastern Alps occupying a good 60 percent of its territory. The River Danube flows for about 350 kilometers from west to east through the northern part of the country, adding to its allure as a tourist destination.
