France has been the world's most popular tourist destination for over twenty years. It received 83 million visitors in 2012, although these figures are highly skewed by the number of people who frequent the country for the weekend, particularly to visit Disneyland Paris, Europe's most popular visitor attraction. All these people come to France for many a reason: its cities contain some of the greatest treasures on the continent, its countryside is prosperous and well-tended and it boasts dozens of major tourist attractions. France is one of the most geographically diverse countries in Europe, containing areas as different from each other as urban chic Paris, the sunny French Riviera, long Atlantic beaches, the winter sports resorts of the French Alps, the castles of the Loire Valley, rugged Celtic Brittany and the historian's dream that is Normandy. The country seduces travellers with its unfalteringly familiar culture, woven around cafe terraces, village-square markets and lace-curtained bistros with their plat du jour chalked on the board.  France citizens enjoy a high standard of living, and the country performs well in international rankings of education, health care, life expectancy, civil liberties, and human development.
