What is the most famous thing about Santorini? The caldera, of course. Apart from a visit to the magical villages of the caldera, treat yourself to another thrilling volcanic experience - trip to Nea Kameni, the small island where you can see a real crater and swim in thermal springs. Spend a day on Thirassia and take a look at Santorini from a different point of view. Watch the sunset from the lighthouse of Akrotiri and compare it to the sunset in Oia.
But Santorini is not only caldera. The archeological site of Ancient Thira and the prehistoric settlement of Akrotiri are of great historical importance and deserve your attention in case you are interested in history, and the extraordinary Red beach will show you the other face of the volcano.
