The spectacular landscape of Santorini is a result of several volcanic explosions! Most of its impressive rocky cliffs are very dark, almost black, because its simply frozen lava. With these volcanic explosions, all kinds of materials and minerals where spread all over, so you can also see some brown, light yellow, white and red rocks around the island.
Here you can see the famous Red beach on the south coast of the island. If you think this colour in the photo is “too much” or oversaturated, wait till you see it with your own eyes!
