Crescent-shaped Santorini is one of Greece’s most popular islands with good reason. It is famous for its sensational blazing sunsets, the archeological ruins called Akrotiri or the Greek Pompeii, beautiful whitewashed villages and unique volcanic beaches. What is most unique is what mother nature left behind. The sight of Santorini’s flooded caldera, a volcanic crater that sits in the depths of Aegean, can be perfectly viewed from the clifftop towns of Fira and Oia. The vantage point from these whitewashed villages, at 1,100 feet high, is simply spectacular. There, beautiful and traditional cave hotels have been built into the landscape and spectacular views are guaranteed from the many restaurants, bars and cafes built there.
