Kayak Laguna Grande: Bioluminescent Bay Night Tour in Fajardo, Puerto Rico
Paddle through mangrove tunnels and watch the lagoon come alive—each stroke stirring bioluminescent plankton into electric blue trails. This 90-minute guided tour from Fajardo is intimate, educational and requires minimal experience.
The Experience
Before You Go
Arrive 30 minutes early
Check-in at Kayak Village under the yellow awning at least 30 minutes before departure to complete waivers and gear checks.
Expect to get wet
Wear quick-drying clothing and water shoes; a change of clothes in your car is a good idea after the tour.
Mind the weight limit
There is a strict 225 lb (102 kg) per-person weight limit—staff will check before boarding so plan accordingly.
Keep lights low
Use a red-filtered headlamp or keep lights off to preserve night vision and maximize bioluminescence visibility.
Local Knowledge
Hidden Gems

Conservation Note
Tour operators enforce no-touch policies and limit lighting to reduce disturbance; visitors are encouraged to use reef-safe sunscreen and keep trash out of the mangroves.
The lagoon’s mangrove system has supported local fisheries and navigation for generations; modern tours emerged in the late 20th century as ecotourism grew.

Common Questions
How bright is the bioluminescence?
Brightness varies nightly and seasonally; on peak nights the water will glow clearly with every paddle stroke, but visibility is never guaranteed as it’s a natural phenomenon.
Can I take photos?
You can, but low light makes it difficult—use long exposures with your phone in a sealed bag or a camera on a tripod; keep flashes off to avoid disturbing others.
Are children allowed?
Yes—children 6–14 must share a tandem kayak with an adult, and 15–17-year-olds must be accompanied by an adult on the tour.
What should I wear?
Quick-drying clothing and secure water shoes are best; expect to get wet and bring a towel and change of clothes for after the tour.
What if there’s sargassum or poor visibility?
Sargassum may be present seasonally and can carry an odor but is harmless; guides may use tarps or postpone tours if visibility is too low or conditions are unsafe.
What is the cancellation policy?
Full refunds are available if you cancel at least 24 hours before the scheduled departure; tours may also be canceled for bad weather or insufficient participants.
