Argentina is a South American country, second in size on the continent after Brazil and eighth in the world. Argentina occupies a continental surface area between the Andes mountain range in the west and the southern Atlantic Ocean in the east and south. It shares borders with Paraguay and Bolivia in the north, Brazil and Uruguay in the northeast, and Chile in the west and south. Tourism in Argentina is favoured by its ample and varied natural assets, by its cultural offer, and by its high exchange rate to foreign currencies. In 2005, according to the National Institute of Statistics and Census, tourism from abroad grew 12% and became the third largest source of income for the country, producing 3,254.5 million USD. There were about 4 million visitors, and for the first time more foreigners visited Argentina than Argentinians travelled abroad. For the first quarter of 2006 it was recorded about 600,000 foreign tourists. Of these, 31% came from Europe, 19% from the United States and Canada, 14% from Brazil, 9% from Chile, 3% from other neighbouring countries, and 14% from the rest of the Americas; the rest of the world accounted for 9%.
