Puerto Rico is one of the few places on Earth to be home to Pyrodimium Bahamense, a microscopic plankton that produces a natural light when disturbed. Join a kayak team and paddle your way through a Mangrove-lined “river” at dusk to the bay, where darkness falls and each stroke of the paddle and jumping fish illuminate the water. Quite the once-in-a-lifetime experience. Most of the kayaking is in the dark, with just glow sticks highlighting the other kayakers. Young children afraid of the dark may not like this trip, as well; one young boy could be heard crying and begging his father to take him back to shore. Keep this activity for your ‘tweens and teens, who will love it!
