Home to the counties of Canada, Greenland, Mexico and the United States of America (USA), North America is bordered by the Arctic Ocean (north), the Atlantic Ocean (east), the Pacific Ocean (west) and South America (south). North America is the world’s third-biggest continent. The tropical beaches of Mexico draw thousands of sun-seeking holidaymakers each year, while in Canada, the capital city of Ottawa competes in the world of tourism with Calgary, Montreal, Niagara Falls, Quebec City, Toronto and Vancouver. The USA is the world’s leading country and is located in North America, comprising some 50 large states and some of the most important and powerful cities in existence. Iconic landmarks in the USA are in plentiful supply and include the Statue of Liberty in New York, San Francisco’s Golden Gate Bridge, the Mount Rushmore National Memorial of South Dakota, and the White House in Washington DC, the American capital. Many holidaymakers tend to pay a visit to the sunny state of California, exploring the spreading city of Los Angeles and checking out its enticing Malibu Beach scene. The theme-park state of Florida is especially suitable for families, who often choose to vacation in Orlando.
