Argentina is a federal state located in southern South America, with a vast land area of more than 3,500 km from north to south. Buenos Aires, the capital, is the birthplace of the passionate tango, and visitors can enjoy the colorful cityscape and art scene, as well as indulge in specialty foods such as asados, empanadas, and wine. Blessed with unspoiled nature, including the Andes Mountains and Iguazu Falls, the cities of Ushuaia, the southernmost city in the world, and El Calafate, facing a glacial lake, are also attractive in their own ways as bases for nature exploration.
