Santorini is a stunning Greek island in the Aegean Sea known for its dramatic volcanic cliffs and panoramic views. The island features iconic whitewashed buildings and brilliant blue domes perched high above a flooded caldera. It attracts millions of visitors with its world-famous sunsets and unique black-sand beaches.
