Machu Picchu of Peru

Machu Picchu's 12 acres of mysterious temples and exquisite terraces are perpetually shrouded in cloud tufts, proving that this ancient site of Peru's Urubamba Valley still lives up to its reputation as the “Lost City of the Incas.” Or at least it seems like it from the pictures. In reality, this ancient city is always overrun with hikers exploring the Inca Trail or catching the view from the Temple of the Sun. So come with plenty of camera film and patience. For fewer crowds -- though not by much -- visit between October and April.
