The island of Santorini has been shaped by the activity of its volcano, which is now dormant. Some of its beaches are therefore pebbly, while others are covered in black sand. Given the sharp relief on the west coast of the island, Santorini's beaches are to be found along its east coast.Do not expect tropical beaches though, as Santorini's coastline offers nothing of the kind, but this does not detract from the beauty of the landscape.
Kamari beach is located some 6 mi from Fira and is a black sandy beach stretching about 3 mi along the coast. A promenade runs along the seafront, and the fairly peaceful Monolithos beach, just up the coast, offers a similar landscape to that found at Kamari. The black sandy beach of Perissa is 9 mi south east of Fira and covers more than 4 mi of coastline. It is particularly lively in the summer due to its many shops, bars and restaurants. However, if you want to do something different, head for the red beach. This is also a black sand beach (with crystal-clear water), but it is surrounded by huge red cliffs and can only be reached by foot or caïque. One of Santorini's most famous and most beautiful beaches, it is located not far from Akrotiri. Vlychada is in the Perivolos region and is often the least busy of the island's beaches. There are also two pretty beaches in the north that are usually frequented by tourists staying in Oia. Ammoudi beach is located directly below Oia, on the north-western tip of the island, while Armeni beach is a bit further up.
