Trip Description

Awesome Night time Bioluminescent, Bio Bay Kayaking Trip at the “Laguna Grande” in Fajardo, Puerto Rico!

Prepare yourself for an experience of a lifetime! Your eyes won’t believe what they are seeing; you will wonder… Is it magic? A hallucination? Hollywood special effects? Then you realize that these are truly enchanted waters of Puerto Rico!

It is a great experience, kayaking in complete darkness, paddling as a couple until from one moment to another the water begins to shine and more and more intensely … then you put your hand in the water and see how it transforms into light ! Enjoy and remember forever as it is not easy to take photos due to lighting conditions.

The only company that features a Marine Biologist as your field guide. We will explain all the processes involved and the unique conditions required for this supernatural phenomena to occur. Your Marine Biologist will also explain how this delicate ecosystem maintains a pure balance and what must be done to preserve and protect the Bio Bay “Laguna Grande”…a very special place on Planet Earth!

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. 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.

  • All required safety equipment, specialized equipment (2 person kayak etc.),
  • kayak “Lesson 101” before the trip

Meeting time: 5:10pm & 7:15pm (Times might change depending the season. If so we will contact you in advance.)

 This is a 2-person kayak tour. Maximum combined weight limit is 400 pounds.

In order to best appreciate the bioluminescent phenomena our tours run at sunset and early evening and it can get quite dark in the mangrove canal. So, if you are afraid of darkness, a first time kayaker, or have small kids we strongly suggest taking the earlier, sunset trip. This way you can see where you are going, get use to the environment and sharpen your kayaking skills.

Due to the immense popularity the Bio Bay tour, at times can get crowded. It’s not uncommon to meet up with other tour groups waiting to access the canal leading to the lagoon. There can be bumping other kayaks along the way. When crowded conditions warrant, will provide extra guides for your safety.

Please keep in mind that this tour takes place in a natural environment and that the bioluminescent phenomenon, although rare, can be seen year round. The intensity of brightness is unpredictable and can vary. Most important – the glow is always there! ENJOY THE SHOW!

For safety reason, children under 6 years old and pregnant women CAN’T participate on any of the kayaking excursions.pregnant women, kids under 6 years old or those who have epilepsy, back problems, heart conditions, dizziness, recent surgery or any other condition that may put life in risk are not allowed to participate. Maximum combined weight is 400 pounds (approx. 200 pounds per person). Please help us make this a pleasant experience for all. Prepare for Adventure!!!
