Our approx. 2-hour and 15 minutes (including check-in) guided bio bay CLEAR BOTTOM KAYAK excursion  includes interesting interpretations about the reserve’s 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 jealous of the glowing water below as it tries to catch up with streaking meteors and impressive constellations!

Join JAK’s 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!

It is the client’s responsibility to arrive to Vieques island on time for their reserved activities or Bio bay tour. Travel delays to Vieques do not constitute a reason for refunds. 

Our recommendation is to fly into Vieques and/or to travel one day prior to reduce your stress and enjoy an extra Vieques activity or beach time! If you are a stress junkie and will travel to Vieques the same day of your tour by the Puerto Rico Ferry, we highly recommend traveling in the morning to avoid delays especially during the high season of December through April.

You may check ferry departure times and purchase tickets at PuertoRicoFerry.com. Please note, PR Ferry only sells ~20% of the tickets online. All other tickets must be purchased at the terminal window. Please read their cancellation policy as we provide this information as a courtesy.

The tour is not cancelled on rainy days, as Puerto Mosquito is almost completely enclosed by a mangrove forest so it is still safe and the water is still glowing under the rain. We make all the determinations about weather cancellations however, so please call us according to your applicable courtesy period  if you decide the weather might not be acceptable, as you will be charged if the trip goes out and you do not cancel your reservation according to our cancelation policy. 

JAK Water Sports and Rental reserves the right to cancel or reroute any tour due to acts of nature or unforeseen circumstances that would hinder our ability to safely run a trip. If we are unable to provide you with another trip, any money paid will be fully refunded.

Flip-flops or Crocs. To help keep our clear bottom kayaks clear and scratch free, you will remove your shoes on the shoreline. We will help you to store them in the kayak.

Please leave large bags at your lodgings as there is not storage on the kayaks or the meeting place. If you bring a small bag, please take precautions to keep it dry as this is a water activity.

First time kayakers are welcome and as most of our clients are first timers, we provide a kayak briefing and paddling instruction before every excursion.

Our kayaks have a combined weight limit of 385 lbs.  If you need special accommodations, please inform us at the time of your booking so that we can provide them. JAK Water Sports reserves the right to assign kayaks as needed.

JAK Water Sports operates in compliance with PR DNER regulations. There are no tours of the Vieques bio bay the day before the full moon, the day of the full moon, and the day after the full moon each month. Some months have two full moons.

This tour takes place in a natural environment. Although rare elsewhere, the bioluminescent phenomenon can be seen year-round in Vieques, however, all natural ecosystems are dynamic and their conditions can vary. Puerto Mosquito is known as a bright and stable bioluminescent bay, but the intensity of the glow may fluctuate due to unpredictable natural changes beyond our control. Most important – the glow is always there! ENJOY THE SHOW!
