Experience the major sites of this quintessential Greek island on a guided walking tour. Visit the quaint village of Oia and stroll through the narrow, cobblestone lanes, viewing the brilliantly whitewashed buildings, shops, cafés and blue-domed churches. Then, sample local wines at a neighboring vineyard and learn about the effects of Santorini's rich, volcanic soil and microclimate on the rare Assyrtiko grapes. Thrill to the views atop Mt. Prophet Elijah, 2,000-feet above sea level and home to the monastery that shares its name. A traditional Greek lunch is a welcome respite in your day before you explore the island's oldest Byzantine church, which has heroically withstood raids, earthquakes and volcanic eruptions. Photograph the famed black sand beach in the cosmopolitan area of Kamari Village. Your final stop is Fira, the capital of Santorini, and you'll ride the town's aerial cable cars (ticket provided) back down to port to meet your tender.
