9Cinque Terre, Italy

Cinque Terre, a string of five colorful seaside villages along the Italian Riviera, is a UNESCO World Heritage Site.

Its dramatic cliffs and crystal-clear waters make it a popular destination, but the small size of these villages means they cannot handle large crowds. In response, the local government has introduced measures to limit the number of visitors, especially during peak seasons.
These restrictions aim to protect the fragile environment and maintain the villages’ charm.
