During the day, Laguna Grande in Fajardo looks like other bays along the tropical Puerto Rican coastline. But come nightfall the bioluminescent lagoon glows fluorescent, thanks to pyrodinium bahamense, microscopic plankton that thrive in its shallow Caribbean waters and glow when disturbed.

Experience an intimate evening in nature! Not for the faint of heart, this magical paddle through the mangrove channel simply can not be duplicated. Far from the sights and sounds of San Juan, the stars and moon will light your way on this journey through the dark. As you navigate through this natural tunnel and into Laguna Grande, the water will begin to sparkle and dance under your paddle! Dip your hand in or splash water into your kayak, anything that contacts this micro organism will activate its defense mechanism and cause it to glow! No LED's or man made effects, just the natural phenomenon of bioluminescence in the calm waters of this protected habitat. Without the ability of cameras to capture the effect, this is truly a must see event!!
