Nestled between the Caribbean, the South Pacific and the South Atlantic Oceans, South America is one of the most culturally rich and geographically diverse continents. The world's biggest rainforest and the second longest river (Amazon), the ruined Inca City of Machu Picchu in Peru and the vibrant cosmopolitan cities of Rio de Janeiro and Buenos Aires are just a few highlights that draw millions of travellers from all over the world.
