| This vast region south of Buenos Aires begins at the Rio Colorado and stretches to the Straits of Magellan. It encompasses interior mountains and glaciers in the provinces of Rio Negro and Neuquen, sandy beaches on its Atlantic coast, and forests of beechwood and monkey puzzle trees where it meets the Andes. The beauty of Patagonia has been preserved in several national parks.  Iguazu falls are the second largest in the world after Victoria Falls in Africa and are deservedly one of the seventh wonders of the world. Their height isn't so inspiring as is their length - the falls seem to go on and on in the distance. When the water level of the river is high, the whole ridge is almost covered in the huge expanse of water pouring over.  | |
