Lighten up in one of the world’s brightest bioluminescent bays

Scoop the water into your hands as you kayak or swim—it’s like a thousand twinkling stars energizing your skin. Moving through microscopic organisms (called dinoflagellates) in this protected bay causes them no harm; it merely triggers a strong blue glow best seen on a moonless evening.
