Starting from the top to the bottom of this fascinating continent, the weather swings from constant heat at the equator to blustery wind and cold at the bottom tip of Patagonia.  The raw beauty of the glaciers and the fascinating desert of Atacama juxtaposes against the Amazon River, wine country and the Andes mountain range.  Visit the ancient city of Machu Picchu or the bustling cities of Sao Paulo, Santiago and Buenos Aires for the varied flavor of South America.  Ecuador strictly limits their Galapagos Islands to keep the ecology of the region in balance. For the best view of a natural wonder see Iguassu Falls from a boat, which encompasses the borders of Argentina, Brazil and Paraguay.
