With dramatic views of classic whitewashed houses clinging perilously to the side of the caldera and stunning beaches of white and red sand or black pebbles, it’s no wonder this may be the most photographed scenery in the world. Visit Ancient Akrotiri, the archeological site of a town frozen in time by ash from an eruption 3,600 years ago. Also worth a day trip is the Volcano of Santorini Palea (old) Kameni and Nea (new) Kameni , two small islands of black lava positioned in the centre of the basin of Santorini.
