Santorini is one of the Cyclades islands in the Aegean Sea. It was devastated by a volcanic eruption in the 16th century BC, forever shaping its rugged landscape. The whitewashed, cubiform houses of its 2 principal towns, Fira and Oia, cling to cliffs above an underwater caldera (crater). They overlook the sea, small islands to the west and beaches made up of black, red and white lava pebbles.
The beautiful Perissa Beach lies at the base of Mesa Vouno Mountain that separates Perissa from Kamari and on its top you can admire the eminent archaeological site of ancient Thera and a superb view. It is about 13 kilometers away from Fira, on the southeast coast of Santorini and is easily accessible by car or bus. The scenery that the black lava sand along with the sandy sea bottom and the dark blue, crystal clear waters compose is impressive. It is one of the longest and most famous beaches in Santorini, a characteristic sight of the volcanic island.
