6Machu Picchu, Peru
Machu Picchu is one of the world’s most iconic archaeological sites, yet it is highly regulated due to environmental and preservation concerns. Tourist numbers are capped daily, and visitors must follow strict routes.
The Peruvian government has implemented timed entry tickets and limits on guide numbers to prevent erosion and damage to this UNESCO World Heritage site. While breathtaking, Machu Picchu demonstrates that even global wonders can become off-limits if over-tourism isn’t managed.
