Before You Go
Four things to consider before your Bio Bay Adventure
Knowing what to expect helps everyone enjoy a safer, more memorable experience.
-
01
Choose the right departure time
Our tours run at sunset and in the early evening, when the mangrove canal can become quite dark. If you are new to kayaking, uneasy in the dark, or travelling with young children, we recommend the earlier sunset trip. It gives you more daylight to get comfortable, see the glow, and build confidence.
-
02
Expect a shared natural space
The Bio Bay is popular, so other groups may be waiting to enter the canal or lagoon. You may occasionally bump into another kayak. When conditions require it, Pure Adventure adds guides to help keep the experience organized and safe.
-
03
The glow is natural and unpredictable
Bioluminescence is a natural phenomenon that can be seen year-round, but its brightness varies. The glow is always present; weather, moonlight, and natural conditions affect how intense it appears. Enjoy the show.
-
04
Review participation requirements
For safety, children under 6 and pregnant women cannot participate in kayaking excursions. Guests with epilepsy, back or heart conditions, dizziness, recent surgery, or another condition that could create risk should not participate. The maximum weight is 240 pounds per person; guests are weighed on site.

A Fun and Beginner-Friendly Bio Bay Tour
I had the best experience with Pure Adventure kayaking trip. Our guides Yadiel, Javier, Eli and Amaury were very funny and made the trip entertaining.
I also had little experience kayaking, but they gave a great demo that calmed all my concerns.
The host Natalia was also very kind and provided free snacks at the end of the trip!!
The price is affordable and you won’t regret picking them for the bioluminescent kayaking!.

TRIPADVISOR REVIEW
Sunset Views, Glowing Waters, and Guides Who Made It Even Better
This tour was great. Amuary, Javier, David, and Yadiel were wonderful guides. They were very helpful, patient, and knowledgeable. Not only did we learn about the bioluminescent bay but got some great tips on Puerto Rican food! We took the 6PM tour.
It was still light and we were able to see the trees in the mangrove channel that leads to the bay. Then, we were able to see the sunset while in the bay. When it was dark, we used a tarp to block the light pollution and be able to see the bioluminescence better.
The trip back though the channel was in total darkness, so we were pleased that we saw it during the daylight. I would definitely recommend the tour with Pure Aventure,

Our guides were knowledgeable, helpful and fun
Our guides were knowledgeable, helpful and fun. Neither my husband nor I had any experience in a kayak but they madesure we weren't left behind. They helped us know what to look for and how to enjoy the most of the sparkles and glowing performances of interacting with the water.
Things to know: it will be very dark, you will walk through shallow water, and you will get a little splashed in your kayak. You will paddle 3 miles with a break halfway through, and there is a weight limit of 240 pounds per person.
Many thanks to our guides Javier, Amaury, Eli, and Catalina, but especially to Yadiel for towing us for a bit when we fell behind!!
