5.00This was an amazing outing. If you can fit it into your plans, do!! It requires some mobility ability to get on and off a boat. You will be in water where you can’t touch, in the dark, but it is so amazing, it’s worth getting over some nerves. We went with 3 kids (7, 3, and 1). All had a fantastic time! We felt very well prepared by the staff and well taken care of during the trip. I recommend bringing snorkel masks and towels in a splash-proof bag. Flotation devices and cold drinks were provided.

5.00Ryan and Nicole were our guides, they were amazing. The Sunset tour was the best you get to experience both Sunset and the Bio bioluminescence. The boat ride was amazing and you can never go wrong choosing Bio Bay Swim and Sunset Charter.

Swimming among the glittering aqua-fireflies

5.00It's best to understand my review in context: even our guide at Mareaito Charters told one member of our party that Mosquito Bay in Vieques "is on a whole other level" compared to our snorkeling at La Parguera's bioluminescent bay. That being so, our La Parguera tour offered clients an opportunity not currently available on Vieques: plunging into the dark waters where the dinoflagellates live and swimming among them. We chose the latest charter departure possible (9 PM), right around moonset on a near-new-moon night & hoped for the best. Our forty-something daughter & her partner described the experience as "pure magic," & frankly, I concur. The bay's waters were surprisingly warm, & our churning feet and swim-strokes glowed like fleeting fireflies beneath us. The not inexpensive fee was a gamble, but the journey into the bay emerged as one of the highlights of our ten-day trip to Puerto Rico. For sheer gratitude, I left a tip for the boat's skipper. Pure bio-magic.
Once in a lifetime magical wxperience

5.00Fiol and Linda were incredible, and took us on a scenic night time boat ride to the bioluminescent bay. They both had excellent experience and guided us to have the best time possible. The bioluminescent algae was such an unforgettable memory, and a once in a lifetime phenomenon to witness. I highly recommend this trip over any other I. Puerto Rico, you will not be disappointed!
Great bio bay tour
