Santorini is one of the most popular tourist destinations in Greece. The croissant-shaped island is dominated by the caldera, a volcanic crater on which the capital of Fira appears perilously perched. Getting there isÂ halfÂ the fun. From the small port of Skala visitors have three options to the top: a quick lift in the cable car, a ride on a donkey, or an arduous walk on foot. (I chose the cable car, thank you.) From a vantage point 1,000 feet above the sea the largely pedestrianized town boasts panoramic views overÂ theÂ submerged – yet still very much active – Â volcano.
