The catamaran slips away from Vlychada marina with a low, rhythmic thrum — sea spray cooling your forearm and caldera cliffs rising like folded pages to the north. Sunlight hits volcanic rock in abrupt flashes of red and black as the captain threads the boat past Red Beach and White Beach, places unreachable by foot and best seen from the water.
