• Santorini, Greek Islands, Greece


Scenic, seismic Santorini is one of the world's most dramatic islands: a flooded caldera (collapsed volcanic crater) with a long, steep, colorfully striped arc of cliffs, thrusting up a thousand feet above sea level. Sometimes called "The Devil's Isle," this unique place has captured visitors' imaginations for millennia and might have partly inspired tales of Atlantis. But the otherworldly appeal of Santorini doesn't end with its setting. Perched along the ridgeline is a gaggle of perfectly placed whitewashed villages, punctuated with azure domes that make this, undeniably, one of Greece's most scenic spots. If this place didn't exist, some fantasy painter would have to conjure it up.
