Greece Tourism Hits Record Despite Mediterranean Heat Crisis

Despite extreme summer temperatures, Greece attracts record tourist numbers, forcing a rethink of its overcrowding and sustainability strategy.

Hot and Crowded: Greece Wrestles With the Paradox of Too Much Success

Greece received a record 35 million international visitors in 2025, generating tourism revenues of approximately €22 billion and maintaining its position as one of Europe's most visited destinations despite — or in some ways because of — the extreme summer heat that has characterised recent Mediterranean summers. The Greek tourism industry's ability to maintain growth through conditions that have deterred visitors to some competing destinations reflects both the enduring appeal of Greece's extraordinary cultural, historical, and natural attractions and the success of marketing efforts to diversify the visitor season toward spring and autumn months when temperatures are more manageable.

The record visitor numbers have, however, intensified debates about the sustainability of mass tourism in destinations that are already showing clear signs of overcrowding stress. Santorini and Mykonos, the two most visited island destinations, have implemented or are debating visitor caps that would limit daily arrivals during peak periods. Residents of central Athens have been vocal about the impact of vacation rental platforms on housing availability and prices in the city's historic neighbourhoods. Environmental organisations have documented significant damage to sensitive marine and coastal ecosystems from tourism activities including powerboat traffic, anchor damage to seagrass beds, and inadequate waste management at high-visitor coastal sites.

The Greek government has responded with a new sustainable tourism strategy that seeks to address these concerns while protecting the economic contribution that tourism makes to a country that has only recently emerged from years of severe austerity. The strategy includes incentives for visitors to travel to less-visited destinations, investment in tourism infrastructure quality outside the main hotspots, environmental protection requirements for tourist facilities, and a visitor levy specifically earmarked for environmental restoration and cultural heritage protection.
