Though it seems like magic, there’s a scientific explanation for the glowing blue that appears. Millions of microorganisms called dinoflagellates flock to the lagoon’s unique combination of mangroves and salt and fresh water. Agitation oxygenates the chemical luciferin embedded in the algae cells, shedding an illuminating glow. Treat yourself to an after-dark cruise around the lagoon and a dip in the warm, shallow water. Tours include round-trip transport from your hotel.
