The motorboat eases off the reef and the island appears like a green coin rimmed in white sand — small, private, and surrounded by water so clear the ocean seems to have a bottom you could walk on. You slip a mask over your face and the boat's hum becomes background; beneath the surface, parrotfish chrome the coral, a hawksbill turtle glides with slow deliberation, and the reef opens like a living wall inviting you through.
