Ancient architectural wonders combine with whitewashed towns, beaches, and abundant sunshine to make the Greek Isles a highly desirable cruising destination. The most magnificent scenery belongs to Santorini, where your ship sails into a bay that is actually a giant caldera, created when a volcano erupted in 1500 B.C. Multihued cliffs and the 1,000-foot-high town of Fira complete the view.
