The advertising on their website (and some other similar websites) is deceiving. If you expect to find yourself in the middle of blue glowing plankton you will be disappointed a lot. There is nothing to see in the lagoon (the water is completely dark), only if you stir the water with a stick you see something - in our case... More

The young lady was helpful called me back when she realized she cancelled the entire reservation. My refund was processed quickly. As far... More

I had a bad experience with them starting from the booking and the very rude young lady working on it. Then, I think it would be important to point out for European citizens that they require your full card details includjng pin by phone without any kind of guarantee, bill or secure way to provide this kind of information (not...

This is a must-do in Puerto Rico! My two friends and I came to puerto rico for a relaxing trip and this activity was the most recommended. I found BioIsland here on Trip Advisor and am so glad I booked it. At first we really wanted to go on the tour in the kayaks but decided after a restful day... More

I took my family here. Hector our driver picked us up from San Juan and drove us to Fajardo, approximately an hour ride. As he was passing locations, he would explain and describe them. He was the best tour guide I've ever had and we travel ALOT! Once we got to Fajardo, he took helped us get ready for the... More

This is a must have experience while in Puerto Rico. I decided to book with Bioisland because I was travelling with my two boys, ages 8 and 10, and was concerned they would have difficulty kayaking. This was definitely the right decision for them. They found this experience truly magical, as did I. We were captivated as soon as we... More

My 10 year old daughter and I had a great time with BioIsland. I was a little worried about Kayaking with her through the dark mangrove trees so decided on the boat. The crew was really great. As we were going through the mangroves the crew pointed out Iguanas in the trees and other wildlife. We went when there was... More

The decision to book our BioBay excursion with BioIsland made our trip to San Juan. You will find no better way to enjoy this once in a lifetime experience. Captain Jeff and Our tour guide Mario shared their wealth of knowledge with the group and made this a truly enlightening experience. Despite what you may read in some other reviews,... More

My teenage daughter and I took this tour. I reserved online after hearing about the electric boat on another travel website. So glad I did, not so sure we would have been ready for adventure of kayaking thru the dark mangroves. Saw many jealous kayakers on the way! We took the last tour of the evening and it ran about...

We enjoyed our tour but if you are expecting to see the brilliant blue light shown on the company website that is not what you will see! They even admit those are pictures taken with an slr camera. That being said, the tour guide Mario and captain Jeff were very friendly and super informative. Going through the mangroves is pretty... More
