You push off from Vlychada as the Aegean wind teases the canvas and Santorini’s cliffline slides aft—white houses and blue domes shrinking into a dramatic crescent. The catamaran threads the rim of the caldera, the water changing from deep cobalt to the clear turquoise of hidden coves, and the captain calls a stop at Red Beach where volcanic cliffs dare you to climb their scarlet faces and jump in.
