The day begins with the hum of an outboard and the sun slicing across water so clear it looks lit from within. A 30-minute boat ride delivers you to the Blue Cave: a collapsed lava tube where crystalline water catches the light and invites a swim. Salt and limestone touch your skin; the cave's cool interior muffles voice and thought.
