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. Pure Adventure 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.

The Bio Bay Adventure tour is one of Puerto Rico’s most popular. There are four things that our guests need to take in consideration:

1) 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.

2) 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, Pure Adventure will provide extra guides for your safety.

3) 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!

4) 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 in PURE ADVENTURE tour. Maximum weight per person is 220 pounds. Guests will be weighed on site. Please help us make this a pleasant experience for all. Prepare for a Pure Adventure!!!
