1. San Juan: Bioluminescent Glass-Bottom Kayak Tour by Night
Embark on a nighttime adventure into the waters of the Laguna Grande and see millions of glowing plankton. Paddle in a two-person glass-bottom kayak (except on Tuesdays, when regular kayaks are used) for approximately 30-minutes through the mystical mangrove channels leading to the natural reserve of the Laguna Grande. See the microscopic plankton capable of producing natural light at the touch of your hand. Explore these amazing organisms up close as your professional guide takes you on a journey to discover all their secrets. Learn how this fragile and unique ecosystem maintains a perfect balance of life, and what you can do to protect such a special place. Paddle in this safe and closed environment, and watch as the water comes alive with millions of glowing plankton. Be aware that the bio bay is an unpredictable natural phenomenon that may be influenced by multiple factors. Bioluminosity levels can vary from very visible to minimal or none without any prior notice. The full moon phase may also affect the visibility of the bioluminescence. In the event of this happening, alternate methods such as the use of a tarp will be incorporated in order to appreciate it.
