Peru is South America’s third largest country, covering 1,285,215 sq. km., and can be divided into three distinct geographic regions. The best known of these is the central high sierra of the Andes, with its massive peaks, steep canyons, and extraordinary pre Columbian archaeological sites. The Andes are still one of the world’s most unstable mountain ranges, with frequent earthquakes, landslides, and flash floods. Despite such instability, the Andes are also the site of the most fascinating pre-Columbian cities of South America-like the great city of the clouds, Machu Picchu.
