The volcanic beaches of Santorini are completely different from the typical golden beaches found across Greece. Shaped by powerful volcanic eruptions, these shores feature black, red, and white sand, dramatic cliffs, and deep blue waters that create a bold and unforgettable contrast.
This is where geology meets the sea.
What Makes Santorini’s Beaches Volcanic?
Santorini’s beaches were formed from lava, ash, and pumice stone following massive volcanic eruptions thousands of years ago. Over time, these materials broke down into colorful sands and steep rock formations, creating beaches that feel raw, wild, and visually striking.
The dark sand also absorbs heat, making the water feel warmer compared to other Aegean beaches.
