Those who love french-fries with their burgers should be thrilled to learn that the potato originated in Peru. The mighty Incas cultivated potatoes in the high altitude of the Andes Mountains. There are over 5,000 registered varieties of potatoes in Peru, being only one reflection of its mega-diversity. Peru, the land of the Incas, awaits travelers with a world of adventure and excitement. The perfectly fitted stones of this glorious empire continue to be the main attraction to people from all over the world. Machu Picchu, the lost city of the Incas rediscovered centuries after the last Conquistador left, remains a web of riddles for the adventurer and the scientist to tackle.
