Visit Chankillo

Set eyes on Río Abiseo, the UNESCO park almost nobody may enter — cloud-forest ruins and a monkey back from the dead

Walk among the 5,000-year-old pyramids of Caral, the oldest known city in the Americas

Descend into the underground galleries of Chavín de Huántar to meet the Lanzón, a 3,000-year-old fanged god

Explore Kuélap, the walled cloud-fortress of the Chachapoya — older than Machu Picchu and nearly empty

Stand under the chullpas of Sillustani — pre-Inca burial towers built finer than the Incas managed

Cross the last Inca rope bridge, hand-woven from grass and rebuilt by four communities every June

More pyramids than all of Egypt.

Stand among the cloud-wrapped ruins of Machu Picchu, the 15th-century Inca citadel perched high above Peru's Sacred Valley
