A low wooden bow parts the blue; the kaiki rocks forward and the caldera cliffs rise like weathered pages. On a five-hour traditional cruise from Vlychada, the wind pushes the boat toward Red Beach’s rust-streaked cliffs, past the white outcrop of White Beach, around the volcanic islets and into the sheltered cove of Ammoudi Bay at Oia.
