Santorini, Greece

The natural beauty of the Greek Islands reaches its crescendo on the island of Santorini, thanks in part to the quintessentially Greek blue and white color palatte of the buildings and churches that cascade down the outside of a volcanic caldera toward the azure waters of the Aegean Sea. If the beauty of the city itself weren't enough, the beaches here are postcard-perfect.
