The outboard hum drops away and the water takes over: an expanse of turquoise that seems to swallow the horizon. The captain eases the boat into a shallow channel around Mnemba Atoll and instructors move with practiced calm, checking masks and guiding guests over the gunwale. When you slip beneath the surface the world shrinks to colour—hard coral fingers, darting anthias, anemones swaying like underwater grass. The sea dares you to look closer; the reef obliges.
