6Santorini, Greece

Santorini, known for its whitewashed buildings and stunning sunsets, has become one of the most famous summer destinations in Europe. However, the island has been struggling with the effects of overtourism, with its small size and limited infrastructure being overwhelmed by the sheer number of visitors, particularly from cruise ships. In response, local authorities have introduced measures such as limiting the number of daily cruise ship arrivals and encouraging tourists to visit in the off-season. Santorini’s fragile ecosystem and the pressure on local resources have made the need for sustainable tourism practices all the more urgent.
