Currently home to Europe’s largest cruise port, the popular Spanish city of Barcelona is restricting port access in an effort to mitigate the impacts of overtourism, an issue that continues to overwhelm many sought-after European destinations.
Following an agreement with local authorities to relocate cruise ships further from the city proper, officials have closed Barcelona’s northern port terminal to all cruise traffic. Passenger cruise vessels will now be required to dock at the Moll d’Adossat pier, situated furthest from the storied city center.
