Santorini is also famous for its colorful beaches, due to the volcano. Perissa hosts the famous black beach, which is also the longest beach on the island, fully organized with umbrellas, beach chairs and shops (among which is a beach bar). Adjacent Perivolos’ beach is also black. Of special interest is the red beach, that is a bit harder to get to. Admittedly, the best beach of Santorini is Vlichada, a very organized beach with red cliffs looming over the swimmers.
