A brisk morning wind pushes salt into your hair as the shop’s wooden ramp clicks underfoot. Guides pass tanks and full-face masks with practiced calm; the boat waits a five-minute ride offshore where the reef drops away. Then the cave appears—an open mouth in the limestone wall where sunlight filters through seawater and turns everything an impossible, electric blue. The light doesn’t just color the water; it seems to lift it, urging divers forward.
