4Dubrovnik, Croatia

Dubrovnik, a stunning coastal city with medieval walls, rose to international fame as a filming location for the hit TV show Game of Thrones.

This surge in popularity has brought an overwhelming number of visitors, especially from cruise ships. The city has responded by limiting the number of visitors allowed into the Old Town each day, and cruise ships are restricted from docking during peak times. Dubrovnik aims to protect its historic sites and ensure a more enjoyable experience for those who do visit.
