The only way to experience The Bio Bay

Only take the experience that I took with the speedboat, because you get a chance to get in the water. It’s very safe, they put a life ring around your waist so you will float. It is a beautiful experience. The water is warm not cold at all. Also if you don’t want to get in the water, you could put your hands in the water and still experience it. Please understand and know what way you wish to experience this remarkable moment. You will not have the same experience on the big boats.

Best experience ever!!

This experience was absolutely amazing. The water was so warm and my skin sparkled like glitter when I pulled my arms out of the water. The sky was gorgeous! We literally saw the Milky Way and the amount of stars in the sky was crazy!!!! I would recommend everyone to do this! It was so dark and the only thing you saw was the sky and when you moved around in the water the water would glow. This was the most exhilarating experience we have ever had. Must try this!

A Must See!!

If you’re looking for a truly unforgettable experience in Puerto Rico, the bioluminescent bay is an absolute must! ✨🌊 It was magical for both the adults and the kids—watching the water glow with every splash is something we’ll never forget. Our captain, Franco, made the entire experience even better. He was knowledgeable, friendly, fun, and made everyone feel safe and welcome throughout the tour. Everyone was amazing and accommodating from the front desk to the captain! This experience see experiences shows my family the beauty of nature and darkness!

Nothing to see at this place

I took the tour by myself, the crew never acknowledged my presence, it was nothing to see, except for the boat ride.

We had an excellent time. Boat ride was smooth. Bio bay was awesome to swim in and see in person. Highly recommend this experience.
