Biobay Tour

"Bienvenidos" to a unique and rare Bioluminescent Experience, an adventure not to be missed while on Vieques Island! Join this fully guided night trip into one of the most amazing natural phenomena of the world with our tandem CLEAR BOTTOM KAYAK! This pristine ecosystem teems with astonishing marine life, inhabiting a secluded bay protected by mangrove forests. You will meet our glowing friends, the Pyrodinium Bahamense, a microscopic plankton capable of producing natural light at the touch of your hand!


Once-in-a-Lifetime Bioluminescent Experience!


At the prescribed time, we meet on the dirt parking lot close to the fisherman dock in Esperanza on road 996   https://maps.app.goo.gl/SCtSEazKoju3xN6w9. Your Eco interpretive guides call the group of kayakers together for a briefing session covering basic kayak handling, rules of the road and the importance of keeping to a minimum any disturbance of the pristine environment of the bioluminescent bay.


Explore these amazing organisms up close in our smaller group excursions led by knowledgeable interpretive guides. Learn how this fragile and unique ecosystem maintains a perfect balance of life, and what we all can do to protect and preserve such a special place on planet earth!


Our 2-hour and 15 minutes approximately guided bio bay CLEAR BOTTOM KAYAK excursion (including check in-time) includes interesting interpretations about the reserve fragile ecological system, star constellations, and a fascinating encounter with millions of bioluminescent organisms. As you glide along in your kayak, experiencing this unusual nighttime phenomenon and seeing how fish light up their path like shooting stars in the water, you might get the feeling that the dark Caribbean sky is getting jealous of the glowing water below as it tries to catch up with shooting stars and impressive constellations!



JAK Water Sports, beyond doubt, can provide you with the best interpretative kayak trip in the Puerto Mosquito bioluminescent bay. Go -"ECO"- explore, conserve, observe with JAK Water Sports and learn with our professional staff about the unique ecosystems, splendid constellations and glowing waters! The adventure to Puerto Mosquito can only be described as magical, creating memories that will last a lifetime!
