3Myrtos Beach, Kefalonia, Greece
Greece may be known for calm Mediterranean waters, but some beaches hide serious risks. Myrtos Beach—one of the most photographed spots in the Ionian Islands—is dazzling with its milky-turquoise water and towering limestone cliffs.
But beneath its beauty lies unexpectedly strong currents, especially on windy days. The steep underwater drop can pull swimmers into deeper waters instantly. Waves can turn violent in a matter of minutes, making swimming risky even for confident swimmers.
