Red minerals accumulated by mountain eruptions eroded by sea water form the unique red beach of Santorini, which is a beautiful beach with charming scenery and isolation from the world. It's very inconvenient to go to Red Sand Beach. We went there with the tour group. There was no road leading to it. Our car stopped by a cliff and the tour guide crossed the mountains to get there. Unfortunately, I didn't go down to the red beach, just took a long view near the red beach, but the scenery is really beautiful, blue sea water, iron sand palm type beach azure sky... Very happy, just now it was sunny, suddenly it began to rain, and then with the rain silk, the rainbow appeared, a large group of adults like children cheered magpies.
