Peru is a nation in South America that is home to an area of the Amazon rainforest and Machu Picchu, an old Incan city high in the Andes mountains. The area around Machu Picchu, including the Sacred Valley, Inca Trail and frontier city of Cusco, is wealthy in archeological destinations. On Peru's bone-dry Pacific coast is Lima, the capital, with a protected pioneer focus and significant accumulations of pre-Columbian craftsmanship.
