Machu Picchu, in the Peruvian Andes at about 2,430m, remains the single most-visited archaeological site in South America. The Pachacuti-era citadel is a UNESCO World Heritage site and one of the New Seven Wonders.

Visiting the site, you work through the Inca urban plan: agricultural terraces first, then the urban zone with the Temple of the Sun, the Royal Tomb, the Intihuatana stone, and the Temple of the Three Windows. Add-ons include the Sun Gate (the Inca Trail finish point) and the Inca Bridge.

Plan the trip with Peruways. Their packages bundle train tickets, Consettur shuttle, citadel entry, and a licensed guide. Guides are the real upgrade — the site has no signage, so without a guide you walk past the key spots.

Group or private tours work; private gives you flexibility on timing and pace, group is cheaper. Either way, book the entry ticket at least a few weeks ahead in high season (May–September).
