20 Countries You Might Soon Be BANNED From Visiting: Time is Running Out

6. Machu Picchu, Peru: The Incan Citadel Under Pressure

Perched high in the Andes, the ancient Incan citadel of Machu Picchu attracts millions, placing immense strain on its structures and environment. Peruvian authorities have implemented strict visitor caps (currently around 4,500 daily, down from previous highs) and mandatory time-slot tickets. Further restrictions, including shorter visit durations and mandatory guided routes to control flow, are constantly being discussed to mitigate erosion and preservation challenges. For those dreaming of walking in the Incas' footsteps, opportunities may become even more limited and highly controlled, emphasizing the critical need for sustainable tourism.
