Join this fully-guided nighttime bioluminescent bay kayak adventure, one of the most memorable experiences in Puerto Rico. After registration process and receiving instructions you will paddle your way in a two person glass-bottom kayak, through the mystical mangrove channels leading to Laguna Grande. This journey may take up to 30 minutes, once you arrive to the area of the lagoon where the bioluminescence can be best experienced, our guides will explain how this entire ecosystem works and will allow you to play with the water to see this effect (swimming not allowed).

Marvel at the Pyrodinium Bahamense, microscopic plankton capable of producing natural light at the touch of your hand! Explore these amazing organisms up close as our professional eco-guide takes you to discover all its secrets. Learn how this fragile and unique ecosystem maintains a perfect balance of life and learn what you can do to protect such a special place. The water comes alive with millions of glowing plankton that must be seen to be believed.
