2Santorini, Greece

The island of Santorini is famous for its stunning sunsets, white-washed buildings, and crystal-clear waters. Its beaches, particularly Red Beach and Kamari Beach, are wonderful. However, the island is frequently overcrowded with tourists, especially during the summer.
Large cruise ships bring thousands of visitors daily, overwhelming the island’s infrastructure. The result is pollution, damage to the landscape, and a loss of the peaceful charm that once defined Santorini’s beaches.
