A port in Barcelona will restrict what cruise ships can stop there.
Barcelona is a popular stop for Britons enjoying a cruise.
From October 22, cruise ships will no longer be able to stop at the northern docks.
This is done to limit the exhaust gases that the city is exposed to.
While ships will still be able to visit Barcelona at other docks, it will limit how many can visit overall.
Ships will need to dock much further from the centre of the city meaning tourists will need to travel more distance to see the Spanish city.
The limit on ships could affect the stops on some popular cruise ships.
Cruises are a great way to see lots of cities in great comfort and luxury.
However, Barcelona isn't the only city to stop tourists from visiting as easily.
Venice banned ships from stopping in the Venice lagoon in 2021.
The Italian city has made further efforts to cut back on visitors as it discussed plans to introduce a daily tax for anyone over the age of 14.
Cruise experts have shared a warning for those who are choosing to travel by ship this year.
