The night swallows sound as the van eases onto the sandy track toward Punta Cocos, and the island exhales: cool salt air, distant mangroves, and a sky so dark the water seems to claim its own light. Guided groups step off the shore and into a shallow lagoon where every ripple answers with a neon pulse — microscopic plankton lighting up like a secret the sea keeps to itself.
