Kayakers entering the bio bay

Join us on a dream-like voyage to an incredibly unique wonderland; the bioluminescent Laguna Grande or Bio Bay, located in a natural reserve on the Northeast tip of Puerto Rico. This pristine ecosystem teems with astonishing marine life, inhabiting a secluded lagoon protected by mangrove forests. The water comes alive with millions of glowing organisms that must be seen to be believed! These microorganisms are known as plankton (that live suspended in the seas between the surface and bottom, at the mercy of the wind and the current). Experience this unusual nighttime phenomena, as you glide along in your kayak you might get the feeling that the dark Caribbean sky is getting jealous of the glowing water below, and tries to catch up with shooting stars and impressive constellations!

There are only four (Bio bay) bioluminescent bays and one lagoon in existence on Earth! Very few people, even Puerto Ricans, are aware of our little known, bioluminescent lagoon. Pure Adventure provides a unique opportunity to visit and actually kayak in the “Bio-Lagoon” known as “Laguna Grande”. This lagoon is the best place to appreciate this phenomenon, being a closed environment, allowing the microorganisms to flourish in bigger concentrations! This glowing effect can be appreciated at any given night. Some nights are more impressive than others…a lot depending on the moon phase. The glowing effect is most appreciated on moonless nights.  Because there are so many organisms, even with full moon you can see the bioluminescence, not to mention how stunning the Lagoon and Mangrove Forests are under a full moon!

Please consult our Puerto Rico Moon Phase calendar.
