The catamaran slips away from Vlychada as wind fills its sails and the caldera cliffs rise like a wall of black and white stone to starboard. Salt air stings and the Aegean pushes the hull into a rhythm: easy, insistent, alive. Passengers lean on the rail to watch Red Beach’s iron-rich cliffs glow, then move on toward the rounded profile of Nea Kameni—the active volcanic heart of Santorini.
