Popular Countries Now Making It Harder for Tourists to Visit in 2025

8. Barcelona, Spain: Suburban Shift & Water Wise Tourism

Barcelona's 2025 plan tackles overtourism by championing its diverse neighborhoods. New, heavily promoted "Barrios Auténticos" routes guide visitors to explore areas like Gràcia or Poble Sec, with incentives for using local businesses. Critically, given ongoing drought concerns, hotels and tourist accommodations now face stricter water usage regulations, and public campaigns urge visitors to be "water wise." This dual approach aims to lessen the strain on central hotspots and vital resources.
