UNESCO called Machu Picchu's problems "urgent," and rampant tourism is the biggest threat to Peru’s main attraction. So why would we suggest you visit if tourism is part of the problem?

Archeological efforts are still ongoing at Machu Picchu, and new discoveries include cemeteries, roads, and a series of agricultural terraces.
