    This is a typical itinerary for this product

    Stop At: Laguna Grande, Cabezas Nature Reserve Northeastern Coast Puerto Rico

    Join this fully-guided nighttime bioluminescent bay kayak adventure, one of the most memorable experiences in Puerto Rico.

    Experience the Pyrodinium Bahamense, a microscopic plankton capable of producing natural light at the touch of your hand (like fireflies)! 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.

    You will paddle your way for 30 minutes each way in a two person glass-bottom kayak, through the mystical mangrove channels leading to the Natural Reserve at Laguna Grande (please read complete description for weight and other restrictions). 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).

    Once tour has concluded light snacks will be available for participants to regain their energy, before heading back to San Juan.

    Duration: 2 hours 30 minutes

    I took the evening tour and would recommend that. The guides are exceptional and you won't have any troubles. It's not pitch black so that you can't see anything.
