The whitewashed, caldera-clinging homes. The blue domed churches. The gorgeous sunsets over the Aegean Sea. It doesn’t matter how many images you’ve seen of Santorini: Even skeptics will be smitten at first sight of this alluring crescent-shaped island. The newly refurbished 490-guest Seven Seas Navigator® is substantial enough to drop anchor in Santorini’s deep harbor—and to have room for amenities like a teak pool deck, specialty lounges and restaurants (offering free unlimited wines and spirits throughout the ship), a casino, and the Canyon Ranch SpaClub®, a fixture on all Regent Seven Seas Cruises ships. During the 7-night Athens to Istanbul sailing, you can disembark to take a scenic drive past windmills to the archaeological ruins of Akrotiri; browse for handmade ceramics and jewelry on a shopping excursion to the town of Oia; or combine a short volcano hike with a hot springs swim and wine tastings.
