Greek islands struggling under a record influx of tourists
ATHENS - Several Greek islands are increasingly struggling under the pressure of tourism and the holiday-home business, according to a study by the University of the Aegean.
On some islands, population density during peak season exceeds that of the greater Athens metropolitan area. The most affected are the popular islands of Santorini and Mykonos, according to the study in late May, reported on in Greek press.
Greece's booming tourism industry hit record visitor numbers last year. According to the Greek central bank, almost 38 million tourists visited Greece in 2025 - nearly three and a half times the country's population.
Infrastructure of many islands at the limit
The study's researchers warn that not only the well-known holiday islands but also numerous smaller islands are barely able to cope with the strain.
Particularly in the summer months, water consumption, electricity demand, waste volumes and traffic problems rise sharply. At the same time, housing for local residents is becoming increasingly scarce, as more and more apartments are being rented out as holiday homes.
The study concludes that while tourism is an important economic factor, it does not automatically lead to balanced development. The researchers therefore call for an expansion of infrastructure, stricter spatial planning and more sustainable tourism management.
Measures against mass tourism
The tourism ministry in Athens is aware of the problem. At the beginning of May, the Greek government announced it would act more decisively against the consequences of mass tourism.
Stricter building regulations are planned for tourist hot spots such as Santorini, Mykonos, Rhodes and Kos. New hotels on the most heavily affected islands are to be smaller in future, with at most 100 beds.
Officials also aim to prevent further buildings being erected haphazardly across the landscape. The coasts are to be protected better, with no building allowed within 25 meters of the sea. Exceptions will be made for access and escape routes.
