We chose bioisland to tour in the electric boat because we had seniors and a child. Best decision ever. Sit back and enjoy the sights while someone else navigates. While all the kayakers are getting stuck and flipping over, you are cruising. The night was so clear you could see the constellations up close. We also saw the Milky Way,... More

Very well organized trip through mangroves. Paddling kayaks during the night is a lot of fun and the BioBay is great. Make sure you go on a moonless night to get the full experience

It is really hard to describe what you can see at the Bio bay. Microorganisms called dinoflagalletes live in very specific environments. They act similar to fireflies so that when you make movement in the water, it sparkes like diamonds. There are only several of them in the world that regularly occur, and there are 2 in Puerto Rico.

Fun trip! Conducted at night, so the navigating of the kayak through a mangrove canal was fun. The bioluminescence bay was very interesting to witness. It took about 1.5 hours. It was a very enjoyable trip.

Visited the BioBay with my family. Not sure of the name of our tour company but the guys were awesome including Michael and "the other Michael." We started off with a nice instructional walk thru of how to use the kayaks, safety precautions, etc.. We then paddled across the shore to a long winding canal through a mangrove forest that... More

Few things on this planet are as real as this. A real treasure that you have to inhale as you experience it. You start off crossing a small bay in your kayak following your host and others. You soon enter a canopy of mangroves where you soon feel that you are in a tunnel. Its not deep but it is... More

Luckily, we found out about the non-kayak option to see the bioluminescent bay at Fajardo. As much as we like kayaking, going on the land-based tour was great. There are three stops on the tour (they drive you around in a shuttle): the lighthouse (Faro de las Cabezas de San Juan); the boardwalk through the mangroves to see the bioluminscence;... More

I did the 9pm tour. Yes it was pitch black and you cannot see ANYTHING but the glow of the water. Do not bring children on this activity. Many adults were having a tough time, especially those with poor eyesight. You are in tandem kayaks, so the front person will need to guide the straight line behind the other guests... More

This was one of the main reasons we planned our trip to Puerto Rico.. There are very few Bioluminiscent bays in the world and Puerto Rico has 3 of them. Plan this trip on a Moonless night, then only you will get to see the glow in water. There are many Tours offering kayaking trips for the Bay, choose a... More

We did the kayak trip. There were 4 of us in my family that participated, two adults and two teenagers (who are very athletic). They put us in the water about an hour after we were scheduled which was fine but seemed to be in a hurry to get done for the night. We were the last tour. Still that... More
