3Santorini, Greece
Famous for its breathtaking sunsets, white-washed buildings, and blue-domed churches, Santorini has become a symbol of Greek island beauty. However, the island’s popularity has led to severe overcrowding during the summer months, especially as cruise ships dump thousands of tourists onto its shores daily. This influx puts a strain on the island’s limited resources, while narrow streets and small villages struggle to accommodate the crowds. Local authorities have implemented measures to control the flow of visitors, such as limiting the number of cruise ship passengers and promoting off-season travel, but overtourism continues to threaten the island’s charm.
