Overtourism Crisis: Most Congested Tourist Destinations Worldwide

Overtourism Crisis: Most Congested Tourist Destinations Worldwide

Planning your next vacation and looking to avoid the crowds? You're not alone. More travelers in 2025 are choosing “calmcations” peaceful holidays centered around relaxation and disconnecting from the constant noise of everyday life. With noise pollution ranked as the second biggest cause of ill health in Western Europe by the World Health Organization, it’s no wonder people are swapping chaotic cities for quieter corners of the world.

However, some places have become so popular that they’re struggling to handle the number of visitors. Tourist hotspots are facing real issues from environmental strain to cultural erosion because of overtourism. If you’re looking for a more relaxing travel experience, knowing where the crowds are can help you steer clear and explore less-visited gems that offer similar beauty and culture.

The Most Congested Tourist Destinations

A recent study compared international visitor numbers with the size of each location to find the most crowded destinations worldwide. The analysis used three key factors:

  • Tourist Density: Tourists per square kilometer.

  • Tourism Pressure on Locals: Tourists compared to the local population.

  • Overall Tourism Intensity: A combination of both metrics.

How to Travel Smarter in 2025

If you're planning to visit one of the top tourist cities, here are a few tips to make your journey more pleasant:

  • Travel in the Shoulder Season: Spring and fall offer better weather and fewer tourists.

  • Visit Lesser-Known Neighborhoods: Even in crowded cities, quieter areas often hold great surprises.

  • Book Early: This helps avoid last-minute price hikes and limited availability.

  • Use Local SIMs or eSIMs: Staying connected helps with directions, bookings, and translations.

(An eSIM provider can offer plans across multiple countries great for international trips without changing cards. Just install it before you leave, and you’re ready to go.)
