Get out on the water for a romantic full-day cruise to Santorini, the volcanic half-moon island in the Aegean Sea. Set sail in the morning for Oia, a picturesque village perched atop an impressive cliff. Enjoy a gourmet lunch in the village of Fira (your expense), before an afternoon relaxing on Perissa Beach. Or, choose an optional excursion to Santorini’s famous volcano. Watch the sun set over the sea as you head back to Heraklion Port.
