What To Expect
After Check-in guides gather group for a brief session covering basic kayaking, rules of the road, and the importance of keeping a minimum disturbance of the environment of the bioluminescent lagoon. Then we launch our kayaks and head for a hidden opening in the mangroves in northern end of the beach. Upon entering the mangroves, we follow a channel for a mile leading to Laguna Grande. Once we enter the laguna your guides gather group for an informative talk about: This unique ecosystem, the flora, fauna, and sea life that inhabits the lagoon, and historical notes. Our bay is very delicate as it depends on the ecosystem surrounding it. Due to climate changes and other factors the bioluminescent bay can reduce its fluorescent lights . This means that the glow is not guaranteed . This all depends on natural or human causes that can affect the organisms. Our company is not responsible for these changes as we do our best to provide a unique experience for all who visit the island.

2.00perhaps my expectations were too high. A picture shows a really cool bio illumination but we had no where near that experience. We were doomed from the start as our group included 2 dozen teens that were screaming and crashing the kayaks. Once in the lagoon, we did not see any illumination. So very disappointing. The guides did a good job but they rope all the kayaks together so it is beyond difficult to see the bio illumination. I don't recommend.

5.00We had a great night time kayak tour through the mangroves. The bioluminescent bay was not as sparkly as we expected but our guides were very knowledgeable and personable. It was a very fun experience that I would highly recommend.

5.00Grab a pouch for your phone! You will get wet. Great Sunset photos. Guides were fabulous. Felt very safe in the Mangrove forest after dark. The Bioluminescent was great.
Only the moon was luminescent (take kayak trip alone)

2.00Frankly disappointed, I won't advise! Choose instead the kayak trip only, it will be just as well for 3x cheaper! Yes it was the disappointment because it was just a kayak trip: arrived for sunset the break time was on the wrong side (the monitor had the right view, we were all strapped in front of him) so advice take pictures of the beautiful sunset when you paddle, do not wait to be strapped... We didn’t see anything luminescent (a third of the moon had to do it) but that’s the risk we understand. We could have waited a little longer because... ...the activity lasted only 1h30 and not 2h... When I say 1h30 it is once their snack is collected and goodbye said (1 mini packet of chips + 1 bottle of water per person) Honestly it’s very expensive the outing even if the staff was very welcoming (you surprise me given the price per person)
We loved it. It was fun,...

Bio Bay - Potential Disappointment

3.00It is important to know that you must have perfect conditions (dark sky, no moonlight) to see the bio glow like you see on their website. Our guides did their best to create a “dark sky” for us by draping a tarp over our heads / kayaks. We still enjoyed the kayaking through the mangroves.

5.00This was a magical evening for our family (2 adults and 2 teens). We read the other more recent reviews with concern - actually, so much concern that we even considered not coming! - but it was nothing like the negative reviews described. Yes, the kayaks are wet docked, so prepare to walk out to them in the dark. There were quite a few flashlights to help. Kayaking was delightful with a very gentle current, the sky filled with stars, and the mangroves cresting a tunnel. There was never complete darkness - there was always a light to follow. The bioluminescence wasn’t as bright as it might be at Mosquito Bay, but it was thrilling for our whole family just the same. We didn’t need tarps, as there wasn’t much moonlight. Overall, 10/10 - we wanted to submit this to thank the guides and set the record straight. It was a truly magical evening for us all!
